5+** unit. This allows many compilers to do optimizations that would not be
6+** possible if the files were compiled separately. Performance improvements
7+** of 5% or more are commonly seen when SQLite is compiled as a single

9+**
10+** This file is all you need to compile SQLite. To use SQLite in other

14+** the text of this file. Search for "Begin file sqlite3.h" to find the start
15+** of the embedded sqlite3.h header file.) Additional code files may be needed
16+** if you want a wrapper to interface SQLite with your choice of programming
17+** language. The code for the "sqlite3" command-line shell is also in a

1136+**
1137+** If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element
1138+** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
1139+** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed. The
1140+** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
1141+** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
1142+** to NULL.
1143+**
1144+** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
1145+** [SQLITE_SYNC_FULL]. The first choice is the normal fsync().
1146+** The second choice is a Mac OS X style fullsync. The [SQLITE_SYNC_DATAONLY]
1147+** flag may be ORed in to indicate that only the data of the file
1148+** and not its inode needs to be synced.
1149+**

1159+** The xCheckReservedLock() method checks whether any database connection,

1164+** The xFileControl() method is a generic interface that allows custom
1165+** VFS implementations to directly control an open file using the
1166+** [sqlite3_file_control()] interface. The second "op" argument is an
1167+** integer opcode. The third argument is a generic pointer intended to
1168+** point to a structure that may contain arguments or space in which to
1169+** write return values. Potential uses for xFileControl() might be
1170+** functions to enable blocking locks with timeouts, to change the
1171+** locking strategy (for example to use dot-file locks), to inquire
1172+** about the status of a lock, or to break stale locks. The SQLite
1173+** core reserves all opcodes less than 100 for its own use.
1174+** A [SQLITE_FCNTL_LOCKSTATE | list of opcodes] less than 100 is available.

1243+** CAPI3REF: Standard File Control Opcodes
1244+**
1245+** These integer constants are opcodes for the xFileControl method
1246+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
1247+** interface.
1248+**
1249+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging. This
1250+** opcode causes the xFileControl method to write the current state of
1251+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
1252+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
1253+** into an integer that the pArg argument points to. This capability
1254+** is used during testing and only needs to be supported when SQLITE_TEST
1255+** is defined.
1256+**
1257+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
1258+** layer a hint of how large the database file will grow to be during the
1259+** current transaction. This hint is not guaranteed to be accurate but it
1260+** is often close. The underlying VFS might choose to preallocate database
1261+** file space based on this hint in order to help writes to the database
1262+** file run faster.
1263+**
1264+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
1265+** extends and truncates the database file in chunks of a size specified
1266+** by the user. The fourth argument to [sqlite3_file_control()] should
1267+** point to an integer (type int) containing the new chunk-size to use
1268+** for the nominated database. Allocating database file space in large
1269+** chunks (say 1MB at a time), may reduce file-system fragmentation and
1270+** improve performance on some systems.
1271+**
1272+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
1273+** to the [sqlite3_file] object associated with a particular database
1274+** connection. See the [sqlite3_file_control()] documentation for
1275+** additional information.
1276+**
1277+** ^(The [SQLITE_FCNTL_SYNC_OMITTED] opcode is generated internally by
1278+** SQLite and sent to all VFSes in place of a call to the xSync method
1279+** when the database connection has [PRAGMA synchronous] set to OFF.)^
1280+** Some specialized VFSes need this signal in order to operate correctly
1281+** when [PRAGMA synchronous | PRAGMA synchronous=OFF] is set, but most
1282+** VFSes do not need this signal and should silently ignore this opcode.
1283+** Applications should not call [sqlite3_file_control()] with this
1284+** opcode as doing so may disrupt the operation of the specialized VFSes
1285+** that do require it.
1286+**
1287+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
1288+** retry counts and intervals for certain disk I/O operations for the
1289+** windows [VFS] in order to work to provide robustness against
1290+** anti-virus programs. By default, the windows VFS will retry file read,
1291+** file write, and file delete operations up to 10 times, with a delay
1292+** of 25 milliseconds before the first retry and with the delay increasing
1293+** by an additional 25 milliseconds with each subsequent retry. This
1294+** opcode allows those to values (10 retries and 25 milliseconds of delay)
1295+** to be adjusted. The values are changed for all database connections
1296+** within the same process. The argument is a pointer to an array of two
1297+** integers where the first integer i the new retry count and the second
1298+** integer is the delay. If either integer is negative, then the setting
1299+** is not changed but instead the prior value of that setting is written
1300+** into the array entry, allowing the current retry settings to be
1301+** interrogated. The zDbName parameter is ignored.
1302+**
1303+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
1304+** persistent [WAL | Write AHead Log] setting. By default, the auxiliary
1305+** write ahead log and shared memory files used for transaction control
1306+** are automatically deleted when the latest connection to the database
1307+** closes. Setting persistent WAL mode causes those files to persist after
1308+** close. Persisting the files is useful when other processes that do not
1309+** have write permission on the directory containing the database file want
1310+** to read the database file, as the WAL and shared memory files must exist
1311+** in order for the database to be readable. The fourth parameter to
1312+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
1313+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
1314+** WAL mode. If the integer is -1, then it is overwritten with the current
1315+** WAL persistence setting.
1316+**
1317+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
1318+** a write transaction to indicate that, unless it is rolled back for some
1319+** reason, the entire database file will be overwritten by the current
1320+** transaction. This is used by VACUUM operations.

1434+**
1435+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
1436+** deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
1437+** will be set for TEMP databases and their journals, transient
1438+** databases, and subjournals.
1439+**
1440+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
1441+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
1442+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
1443+** API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
1444+** SQLITE_OPEN_CREATE, is used to indicate that file should always
1445+** be created, and that it is an error if it already exists.
1446+** It is <i>not</i> used to indicate the file should be opened
1447+** for exclusive access.
1448+**
1449+** ^At least szOsFile bytes of memory are allocated by SQLite
1450+** to hold the [sqlite3_file] structure passed as the third
1451+** argument to xOpen. The xOpen method does not have to
1452+** allocate the structure; it should just fill it in. Note that
1453+** the xOpen method must set the sqlite3_file.pMethods to either
1454+** a valid [sqlite3_io_methods] object or to NULL. xOpen must do
1455+** this even if the open fails. SQLite expects that the sqlite3_file.pMethods
1456+** element will be valid after xOpen returns regardless of the success
1457+** or failure of the xOpen call.
1458+**
1459+** [[sqlite3_vfs.xAccess]]
1460+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
1461+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
1462+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
1463+** to test whether a file is at least readable. The file can be a
1464+** directory.
1465+**
1466+** ^SQLite will always allocate at least mxPathname+1 bytes for the
1467+** output buffer xFullPathname. The exact size of the output buffer
1468+** is also passed as a parameter to both methods. If the output buffer
1469+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
1470+** handled as a fatal error by SQLite, vfs implementations should endeavor
1471+** to prevent this by setting mxPathname to a sufficiently large value.
1472+**
1473+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
1474+** interfaces are not strictly a part of the filesystem, but they are
1475+** included in the VFS structure for completeness.
1476+** The xRandomness() function attempts to return nBytes bytes
1477+** of good-quality randomness into zOut. The return value is
1478+** the actual number of bytes of randomness obtained.
1479+** The xSleep() method causes the calling thread to sleep for at
1480+** least the number of microseconds given. ^The xCurrentTime()
1481+** method returns a Julian Day Number for the current date and time as
1482+** a floating point value.
1483+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
1484+** Day Number multiplied by 86400000 (the number of milliseconds in
1485+** a 24-hour day).
1486+** ^SQLite will use the xCurrentTimeInt64() method to get the current
1487+** date and time if that method is available (if iVersion is 2 or
1488+** greater and the function pointer is not NULL) and will fall back
1489+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.

1611+** deallocates any resources that were allocated by sqlite3_initialize().
1612+** These routines are designed to aid in process initialization and
1613+** shutdown on embedded systems. Workstation applications using
1614+** SQLite normally do not need to invoke either of these routines.
1615+**
1616+** A call to sqlite3_initialize() is an "effective" call if it is
1617+** the first time sqlite3_initialize() is invoked during the lifetime of
1618+** the process, or if it is the first time sqlite3_initialize() is invoked
1619+** following a call to sqlite3_shutdown(). ^(Only an effective call
1620+** of sqlite3_initialize() does any initialization. All other calls
1621+** are harmless no-ops.)^
1622+**
1623+** A call to sqlite3_shutdown() is an "effective" call if it is the first
1624+** call to sqlite3_shutdown() since the last sqlite3_initialize(). ^(Only
1625+** an effective call to sqlite3_shutdown() does any deinitialization.
1626+** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
1627+**
1628+** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
1629+** is not. The sqlite3_shutdown() interface must only be called from a
1630+** single thread. All open [database connections] must be closed and all
1631+** other SQLite resources must be deallocated prior to invoking
1632+** sqlite3_shutdown().
1633+**
1634+** Among other things, ^sqlite3_initialize() will invoke
1635+** sqlite3_os_init(). Similarly, ^sqlite3_shutdown()
1636+** will invoke sqlite3_os_end().
1637+**
1638+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
1639+** ^If for some reason, sqlite3_initialize() is unable to initialize
1640+** the library (perhaps it is unable to allocate a needed resource such
1641+** as a mutex) it returns an [error code] other than [SQLITE_OK].
1642+**
1643+** ^The sqlite3_initialize() routine is called internally by many other
1644+** SQLite interfaces so that an application usually does not need to
1645+** invoke sqlite3_initialize() directly. For example, [sqlite3_open()]
1646+** calls sqlite3_initialize() so the SQLite library will be automatically
1647+** initialized when [sqlite3_open()] is called if it has not be initialized
1648+** already. ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
1649+** compile-time option, then the automatic calls to sqlite3_initialize()
1650+** are omitted and the application must call sqlite3_initialize() directly
1651+** prior to using any other SQLite interface. For maximum portability,
1652+** it is recommended that applications always invoke sqlite3_initialize()
1653+** directly prior to using any other SQLite interface. Future releases
1654+** of SQLite may require this. In other words, the behavior exhibited
1655+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
1656+** default behavior in some future release of SQLite.
1657+**
1658+** The sqlite3_os_init() routine does operating-system specific
1659+** initialization of the SQLite library. The sqlite3_os_end()
1660+** routine undoes the effect of sqlite3_os_init(). Typical tasks
1661+** performed by these routines include allocation or deallocation
1662+** of static resources, initialization of global variables,
1663+** setting up a default [sqlite3_vfs] module, or setting up
1664+** a default configuration using [sqlite3_config()].
1665+**
1666+** The application should never invoke either sqlite3_os_init()

1741+** This object is used in only one place in the SQLite interface.

1743+** [sqlite3_config()] when the configuration option is
1744+** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
1745+** By creating an instance of this object
1746+** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
1747+** during configuration, an application can specify an alternative
1748+** memory allocation subsystem for SQLite to use for all of its
1749+** dynamic memory needs.
1750+**
1751+** Note that SQLite comes with several [built-in memory allocators]
1752+** that are perfectly adequate for the overwhelming majority of applications
1753+** and that this object is only useful to a tiny minority of applications
1754+** with specialized memory allocation requirements. This object is
1755+** also used during testing of SQLite in order to specify an alternative
1756+** memory allocator that simulates memory out-of-memory conditions in
1757+** order to verify that SQLite recovers gracefully from such
1758+** conditions.
1759+**
1760+** The xMalloc, xRealloc, and xFree methods must work like the
1761+** malloc(), realloc() and free() functions from the standard C library.
1762+** ^SQLite guarantees that the second argument to
1763+** xRealloc is always a value returned by a prior call to xRoundup.
1764+**
1765+** xSize should return the allocated size of a memory allocation
1766+** previously obtained from xMalloc or xRealloc. The allocated size
1767+** is always at least as big as the requested size but may be larger.
1768+**
1769+** The xRoundup method returns what would be the allocated size of
1770+** a memory allocation given a particular requested size. Most memory
1771+** allocators round up memory allocations at least to the next multiple
1772+** of 8. Some allocators round up to a larger multiple or to a power of 2.
1773+** Every memory allocation request coming in through [sqlite3_malloc()]
1774+** or [sqlite3_realloc()] first calls xRoundup. If xRoundup returns 0,
1775+** that causes the corresponding memory allocation to fail.
1776+**
1777+** The xInit method initializes the memory allocator. (For example,
1778+** it might allocate any require mutexes or initialize internal data
1779+** structures. The xShutdown method is invoked (indirectly) by
1780+** [sqlite3_shutdown()] and should deallocate any resources acquired
1781+** by xInit. The pAppData pointer is used as the only parameter to
1782+** xInit and xShutdown.
1783+**
1784+** SQLite holds the [SQLITE_MUTEX_STATIC_MASTER] mutex when it invokes

2335+** ^The first argument to the busy handler is a copy of the void* pointer which

2341+** ^If the callback returns non-zero, then another attempt

2347+** or [SQLITE_IOERR_BLOCKED] instead of invoking the busy handler.
2348+** Consider a scenario where one process is holding a read lock that
2349+** it is trying to promote to a reserved lock and
2350+** a second process is holding a reserved lock that it is trying
2351+** to promote to an exclusive lock. The first process cannot proceed

2356+** will induce the first process to release its read lock and allow

2364+** already hold a RESERVED lock on the database file, but it needs

2366+** pages into the database file without harm to concurrent

2411+** CAPI3REF: Convenience Routines For Running Queries
2412+**
2413+** This is a legacy interface that is preserved for backwards compatibility.
2414+** Use of this interface is not recommended.
2415+**
2416+** Definition: A <b>result table</b> is memory data structure created by the
2417+** [sqlite3_get_table()] interface. A result table records the
2418+** complete query results from one or more queries.
2419+**
2420+** The table conceptually has a number of rows and columns. But
2421+** these numbers are not part of the result table itself. These
2422+** numbers are obtained separately. Let N be the number of rows
2423+** and M be the number of columns.
2424+**
2425+** A result table is an array of pointers to zero-terminated UTF-8 strings.
2426+** There are (N+1)*M elements in the array. The first M pointers point
2427+** to zero-terminated strings that contain the names of the columns.
2428+** The remaining entries all point to query results. NULL values result
2429+** in NULL pointers. All other values are in their UTF-8 zero-terminated
2430+** string representation as returned by [sqlite3_column_text()].
2431+**
2432+** A result table might consist of one or more memory allocations.
2433+** It is not safe to pass a result table directly to [sqlite3_free()].
2434+** A result table should be deallocated using [sqlite3_free_table()].
2435+**
2436+** ^(As an example of the result table format, suppose a query result
2437+** is as follows:
2438+**
2439+** <blockquote><pre>
2440+** Name | Age
2441+** -----------------------
2442+** Alice | 43
2443+** Bob | 28
2444+** Cindy | 21
2445+** </pre></blockquote>
2446+**
2447+** There are two column (M==2) and three rows (N==3). Thus the
2448+** result table has 8 entries. Suppose the result table is stored
2449+** in an array names azResult. Then azResult holds this content:
2450+**
2451+** <blockquote><pre>
2452+** azResult&#91;0] = "Name";
2453+** azResult&#91;1] = "Age";
2454+** azResult&#91;2] = "Alice";
2455+** azResult&#91;3] = "43";
2456+** azResult&#91;4] = "Bob";
2457+** azResult&#91;5] = "28";
2458+** azResult&#91;6] = "Cindy";
2459+** azResult&#91;7] = "21";
2460+** </pre></blockquote>)^

2462+** ^The sqlite3_get_table() function evaluates one or more
2463+** semicolon-separated SQL statements in the zero-terminated UTF-8
2464+** string of its 2nd parameter and returns a result table to the
2465+** pointer given in its 3rd parameter.
2466+**
2467+** After the application has finished with the result from sqlite3_get_table(),
2468+** it must pass the result table pointer to sqlite3_free_table() in order to

2506+** the standard C library. The result is written into the
2507+** buffer supplied as the second parameter whose size is given by
2508+** the first parameter. Note that the order of the
2509+** first two parameters is reversed from snprintf().)^ This is an
2510+** historical accident that cannot be fixed without breaking
2511+** backwards compatibility. ^(Note also that sqlite3_snprintf()
2512+** returns a pointer to its buffer instead of the number of
2513+** characters actually written into the buffer.)^ We admit that
2514+** the number of characters written would be a more useful return
2515+** value but we cannot change the implementation of sqlite3_snprintf()
2516+** now without breaking compatibility.
2517+**
2518+** ^As long as the buffer size is greater than zero, sqlite3_snprintf()
2519+** guarantees that the buffer is always zero-terminated. ^The first
2520+** parameter "n" is the total size of the buffer, including space for
2521+** the zero terminator. So the longest string that can be completely
2522+** written will be n-1 characters.
2523+**
2524+** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf().
2525+**
2526+** These routines all implement some additional formatting
2527+** options that are useful for constructing SQL statements.
2528+** All of the usual printf() formatting options apply. In addition, there
2529+** is are "%q", "%Q", and "%z" options.
2530+**
2531+** ^(The %q option works like %s in that it substitutes a null-terminated
2532+** string from the argument list. But %q also doubles every '\'' character.
2533+** %q is designed for use inside a string literal.)^ By doubling each '\''
2534+** character it escapes that character and allows it to be inserted into
2535+** the string.
2536+**
2537+** For example, assume the string variable zText contains text as follows:
2538+**
2539+** <blockquote><pre>
2540+** char *zText = "It's a happy day!";
2541+** </pre></blockquote>
2542+**
2543+** One can use this text in an SQL statement as follows:
2544+**
2545+** <blockquote><pre>
2546+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
2547+** sqlite3_exec(db, zSQL, 0, 0, 0);
2548+** sqlite3_free(zSQL);
2549+** </pre></blockquote>
2550+**
2551+** Because the %q format string is used, the '\'' character in zText
2552+** is escaped and the SQL generated is as follows:
2553+**
2554+** <blockquote><pre>
2555+** INSERT INTO table1 VALUES('It''s a happy day!')
2556+** </pre></blockquote>
2557+**
2558+** This is correct. Had we used %s instead of %q, the generated SQL
2559+** would have looked like this:
2560+**
2561+** <blockquote><pre>
2562+** INSERT INTO table1 VALUES('It's a happy day!');
2563+** </pre></blockquote>
2564+**
2565+** This second example is an SQL syntax error. As a general rule you should
2566+** always use %q instead of %s when inserting text into a string literal.
2567+**
2568+** ^(The %Q option works like %q except it also adds single quotes around
2569+** the outside of the total string. Additionally, if the parameter in the
2570+** argument list is a NULL pointer, %Q substitutes the text "NULL" (without
2571+** single quotes).)^ So, for example, one could say:
2572+**
2573+** <blockquote><pre>
2574+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
2575+** sqlite3_exec(db, zSQL, 0, 0, 0);
2576+** sqlite3_free(zSQL);
2577+** </pre></blockquote>
2578+**
2579+** The code above will render a correct SQL statement in the zSQL
2580+** variable even if the zText variable is a NULL pointer.
2581+**
2582+** ^(The "%z" formatting option works like "%s" but with the

2713+**
2714+** ^This routine registers an authorizer callback with a particular
2715+** [database connection], supplied in the first argument.
2716+** ^The authorizer callback is invoked as SQL statements are being compiled
2717+** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
2718+** [sqlite3_prepare16()] and [sqlite3_prepare16_v2()]. ^At various
2719+** points during the compilation process, as logic is being created
2720+** to perform various actions, the authorizer callback is invoked to
2721+** see if those actions are allowed. ^The authorizer callback should
2722+** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
2723+** specific action but allow the SQL statement to continue to be
2724+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
2725+** rejected with an error. ^If the authorizer callback returns
2726+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
2727+** then the [sqlite3_prepare_v2()] or equivalent call that triggered
2728+** the authorizer will fail with an error message.
2729+**
2730+** When the callback returns [SQLITE_OK], that means the operation
2731+** requested is ok. ^When the callback returns [SQLITE_DENY], the
2732+** [sqlite3_prepare_v2()] or equivalent call that triggered the
2733+** authorizer will fail with an error message explaining that
2734+** access is denied.
2735+**
2736+** ^The first parameter to the authorizer callback is a copy of the third
2737+** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
2738+** to the callback is an integer [SQLITE_COPY | action code] that specifies
2739+** the particular action to be authorized. ^The third through sixth parameters
2740+** to the callback are zero-terminated strings that contain additional
2741+** details about the action to be authorized.
2742+**
2743+** ^If the action code is [SQLITE_READ]
2744+** and the callback returns [SQLITE_IGNORE] then the
2745+** [prepared statement] statement is constructed to substitute
2746+** a NULL value in place of the table column that would have
2747+** been read if [SQLITE_OK] had been returned. The [SQLITE_IGNORE]
2748+** return can be used to deny an untrusted user access to individual
2749+** columns of a table.
2750+** ^If the action code is [SQLITE_DELETE] and the callback returns
2751+** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
2752+** [truncate optimization] is disabled and all rows are deleted individually.
2753+**
2754+** An authorizer is used when [sqlite3_prepare | preparing]
2755+** SQL statements from an untrusted source, to ensure that the SQL statements
2756+** do not try to access data they are not allowed to see, or that they do not
2757+** try to execute malicious statements that damage the database. For
2758+** example, an application may allow a user to enter arbitrary
2759+** SQL queries for evaluation by a database. But the application does
2760+** not want the user to be able to make arbitrary changes to the
2761+** database. An authorizer could then be put in place while the
2762+** user-entered SQL is being [sqlite3_prepare | prepared] that
2763+** disallows everything except [SELECT] statements.
2764+**
2765+** Applications that need to process SQL from untrusted sources
2766+** might also consider lowering resource limits using [sqlite3_limit()]
2767+** and limiting database size using the [max_page_count] [PRAGMA]
2768+** in addition to using an authorizer.
2769+**
2770+** ^(Only a single authorizer can be in place on a database connection
2771+** at a time. Each call to sqlite3_set_authorizer overrides the
2772+** previous call.)^ ^Disable the authorizer by installing a NULL callback.
2773+** The authorizer is disabled by default.

3049+**
3050+** <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw" or
3051+** "rwc". Attempting to set it to any other value is an error)^.
3052+** ^If "ro" is specified, then the database is opened for read-only

3058+** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If sqlite3_open_v2() is
3059+** used, it is an error to specify a value for the mode parameter that is
3060+** less restrictive than that specified by the flags passed as the third
3061+** parameter.
3062+**
3063+** <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
3064+** "private". ^Setting it to "shared" is equivalent to setting the
3065+** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
3066+** sqlite3_open_v2(). ^Setting the cache parameter to "private" is

3327+** KEYWORDS: {SQL statement compiler}
3328+**
3329+** To execute an SQL query, it must first be compiled into a byte-code
3330+** program using one of these routines.
3331+**
3332+** The first argument, "db", is a [database connection] obtained from a
3333+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
3334+** [sqlite3_open16()]. The database connection must not have been closed.
3335+**
3336+** The second argument, "zSql", is the statement to be compiled, encoded
3337+** as either UTF-8 or UTF-16. The sqlite3_prepare() and sqlite3_prepare_v2()
3338+** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
3339+** use UTF-16.
3340+**
3341+** ^If the nByte argument is less than zero, then zSql is read up to the
3342+** first zero terminator. ^If nByte is non-negative, then it is the maximum
3343+** number of bytes read from zSql. ^When nByte is non-negative, the
3344+** zSql string ends at either the first '\000' or '\u0000' character or
3345+** the nByte-th byte, whichever comes first. If the caller knows
3346+** that the supplied string is nul-terminated, then there is a small
3347+** performance advantage to be gained by passing an nByte parameter that
3348+** is equal to the number of bytes in the input string <i>including</i>
3349+** the nul-terminator bytes as this saves SQLite from having to
3350+** make a copy of the input string.
3351+**
3352+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
3353+** past the end of the first SQL statement in zSql. These routines only
3354+** compile the first statement in zSql, so *pzTail is left pointing to
3355+** what remains uncompiled.
3356+**
3357+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
3358+** executed using [sqlite3_step()]. ^If there is an error, *ppStmt is set
3359+** to NULL. ^If the input text contains no SQL (if the input is an empty
3360+** string or a comment) then *ppStmt is set to NULL.
3361+** The calling procedure is responsible for deleting the compiled
3362+** SQL statement using [sqlite3_finalize()] after it has finished with it.
3363+** ppStmt may not be NULL.
3364+**
3365+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
3366+** otherwise an [error code] is returned.
3367+**
3368+** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are

3370+** for backwards compatibility, but their use is discouraged.
3371+** ^In the "v2" interfaces, the prepared statement

3375+**
3376+** <ol>
3377+** <li>
3378+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
3379+** always used to do, [sqlite3_step()] will automatically recompile the SQL
3380+** statement and try to run it again.
3381+** </li>
3382+**
3383+** <li>
3384+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
3385+** [error codes] or [extended error codes]. ^The legacy behavior was that
3386+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
3387+** and the application would have to make a second call to [sqlite3_reset()]
3388+** in order to find the underlying cause of the problem. With the "v2" prepare
3389+** interfaces, the underlying reason for the error is returned immediately.

3842+**
3843+** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
3844+** database locks it needs to do its job. ^If the statement is a [COMMIT]
3845+** or occurs outside of an explicit transaction, then you can retry the
3846+** statement. If the statement is not a [COMMIT] and occurs within an
3847+** explicit transaction then you should rollback the transaction before
3848+** continuing.
3849+**
3850+** ^[SQLITE_DONE] means that the statement has finished executing
3851+** successfully. sqlite3_step() should not be called again on this virtual
3852+** machine without first calling [sqlite3_reset()] to reset the virtual
3853+** machine back to its initial state.

3855+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]

3858+** sqlite3_step() is called again to retrieve the next row of data.
3859+**
3860+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
3861+** violation) has occurred. sqlite3_step() should not be called again on
3862+** the VM. More information may be found by calling [sqlite3_errmsg()].
3863+** ^With the legacy interface, a more specific error code (for example,
3864+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
3865+** can be obtained by calling [sqlite3_reset()] on the

3867+** the more specific error code is returned directly by sqlite3_step().
3868+**
3869+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
3870+** Perhaps it was called on a [prepared statement] that has
3871+** already been [sqlite3_finalize | finalized] or on one that had
3872+** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
3873+** be the case that the same database connection is being used by two or
3874+** more threads at the same moment in time.
3875+**
3876+** For all versions of SQLite up to and including 3.6.23.1, a call to
3877+** [sqlite3_reset()] was required after sqlite3_step() returned anything
3878+** other than [SQLITE_ROW] before any subsequent invocation of
3879+** sqlite3_step(). Failure to reset the prepared statement using
3880+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
3881+** sqlite3_step(). But after version 3.6.23.1, sqlite3_step() began
3882+** calling [sqlite3_reset()] automatically in this circumstance rather
3883+** than returning [SQLITE_MISUSE]. This is not considered a compatibility
3884+** break because any application that ever receives an SQLITE_MISUSE error
3885+** is broken by definition. The [SQLITE_OMIT_AUTORESET] compile-time option
3886+** can be used to restore the legacy behavior.
3887+**
3888+** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
3889+** API always returns a generic error code, [SQLITE_ERROR], following any
3890+** error other than [SQLITE_BUSY] and [SQLITE_MISUSE]. You must call
3891+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
3892+** specific [error codes] that better describes the error.

3969+** If the SQL statement does not currently point to a valid row, or if the

3974+** If any of these routines are called after [sqlite3_reset()] or
3975+** [sqlite3_finalize()] or after [sqlite3_step()] has returned

3977+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
3978+** are called from a different thread while any of these routines
3979+** are pending, then the results are undefined.
3980+**
3981+** ^The sqlite3_column_type() routine returns the

4055+**
4056+** The table above makes reference to standard C library functions atoi()
4057+** and atof(). SQLite does not really use these functions. It has its
4058+** own equivalent internal routines. The atoi() and atof() names are
4059+** used in the table for brevity and because they are familiar to most
4060+** C programmers.
4061+**
4062+** Note that when type conversions occur, pointers returned by prior
4063+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
4064+** sqlite3_column_text16() may be invalidated.
4065+** Type conversions and pointer invalidations might occur
4066+** in the following cases:
4067+**
4068+** <ul>
4069+** <li> The initial content is a BLOB and sqlite3_column_text() or
4070+** sqlite3_column_text16() is called. A zero-terminator might
4071+** need to be added to the string.</li>
4072+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
4073+** sqlite3_column_text16() is called. The content must be converted
4074+** to UTF-16.</li>
4075+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
4076+** sqlite3_column_text() is called. The content must be converted
4077+** to UTF-8.</li>
4078+** </ul>
4079+**
4080+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
4081+** not invalidate a prior pointer, though of course the content of the buffer
4082+** that the prior pointer references will have been modified. Other kinds
4083+** of conversion are done in place when it is possible, but sometimes they
4084+** are not possible and in those cases prior pointers are invalidated.
4085+**
4086+** The safest and easiest to remember policy is to invoke these routines
4087+** in one of the following ways:
4088+**
4089+** <ul>
4090+** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
4091+** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
4092+** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
4093+** </ul>
4094+**
4095+** In other words, you should call sqlite3_column_text(),
4096+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
4097+** into the desired format, then invoke sqlite3_column_bytes() or
4098+** sqlite3_column_bytes16() to find the size of the result. Do not mix calls
4099+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
4100+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
4101+** with calls to sqlite3_column_bytes().
4102+**
4103+** ^The pointers returned are valid until a type conversion occurs as

4333+** CAPI3REF: Obtaining SQL Function Parameter Values
4334+**
4335+** The C-language implementation of SQL functions and aggregates uses
4336+** this set of interface routines to access the parameter values on
4337+** the function or aggregate.
4338+**
4339+** The xFunc (for scalar functions) or xStep (for aggregates) parameters
4340+** to [sqlite3_create_function()] and [sqlite3_create_function16()]
4341+** define callbacks that implement the SQL functions and aggregates.
4342+** The 3rd parameter to these callbacks is an array of pointers to
4343+** [protected sqlite3_value] objects. There is one [sqlite3_value] object for
4344+** each parameter to the SQL function. These routines are used to
4345+** extract values from the [sqlite3_value] objects.
4346+**
4347+** These routines work only with [protected sqlite3_value] objects.
4348+** Any attempt to use these routines on an [unprotected sqlite3_value]
4349+** object results in undefined behavior.
4350+**
4351+** ^These routines work just like the corresponding [column access functions]
4352+** except that these routines take a single [protected sqlite3_value] object
4353+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
4354+**
4355+** ^The sqlite3_value_text16() interface extracts a UTF-16 string
4356+** in the native byte-order of the host machine. ^The
4357+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
4358+** extract UTF-16 strings as big-endian and little-endian respectively.

4360+** ^(The sqlite3_value_numeric_type() interface attempts to apply

6031+** The sqlite3_mutex_held() and sqlite3_mutex_notheld() routines
6032+** are intended for use inside assert() statements. ^The SQLite core
6033+** never uses these routines except inside an assert() and applications
6034+** are advised to follow the lead of the core. ^The SQLite core only
6035+** provides implementations for these routines when it is compiled
6036+** with the SQLITE_DEBUG flag. ^External mutex implementations
6037+** are only required to provide these routines if SQLITE_DEBUG is
6038+** defined and if NDEBUG is not defined.
6039+**
6040+** ^These routines should return true if the mutex in their argument
6041+** is held or not held, respectively, by the calling thread.
6042+**
6043+** ^The implementation is not required to provided versions of these
6044+** routines that actually work. If the implementation does not provide working
6045+** versions of these routines, it should at least provide stubs that always
6046+** return true so that one does not get spurious assertion failures.
6047+**
6048+** ^If the argument to sqlite3_mutex_held() is a NULL pointer then
6049+** the routine should return 1. This seems counter-intuitive since
6050+** clearly the mutex cannot be held if it does not exist. But
6051+** the reason the mutex does not exist is because the build is not
6052+** using mutexes. And we do not want the assert() containing the
6053+** call to sqlite3_mutex_held() to fail, so a non-zero return is
6054+** the appropriate thing to do. ^The sqlite3_mutex_notheld()
6055+** interface should also return 1 when given a NULL pointer.
