* The "generate_series()" SQLite extension is now included by default.
|

One change from the standard implementation is that both the start and

******************************************************************************
|
||||
**
|
||||
** This file implements a C-language subroutine that converts the content
|
||||
** of an SQLite database into UTF-8 text SQL statements that can be used
|
||||
** to exactly recreate the original database. ROWID values are preserved.
|
||||
**
|
||||
** A prototype of the implemented subroutine is this:
|
||||
**
|
||||
** int sqlite3_db_dump(
|
||||
** sqlite3 *db,
|
||||
** const char *zSchema,
|
||||
** const char *zTable,
|
||||
** void (*xCallback)(void*, const char*),
|
||||
** void *pArg
|
||||
** );
|
||||
**
|
||||
** The db parameter is the database connection. zSchema is the schema within
|
||||
** that database which is to be dumped. Usually the zSchema is "main" but
|
||||
** can also be "temp" or any ATTACH-ed database. If zTable is not NULL, then
|
||||
** only the content of that one table is dumped. If zTable is NULL, then all
|
||||
** tables are dumped.
|
||||
**
|
||||
** The generate text is passed to xCallback() in multiple calls. The second
|
||||
** argument to xCallback() is a copy of the pArg parameter. The first
|
||||
** argument is some of the output text that this routine generates. The
|
||||
** signature to xCallback() is designed to make it compatible with fputs().
|
||||
**
|
||||
** The sqlite3_db_dump() subroutine returns SQLITE_OK on success or some error
|
||||
** code if it encounters a problem.
|
||||
**
|
||||
** If this file is compiled with -DDBDUMP_STANDALONE then a "main()" routine
|
||||
** is included so that this routine becomes a command-line utility. The
|
||||
** command-line utility takes two or three arguments which are the name
|
||||
** of the database file, the schema, and optionally the table, forming the
|
||||
** first three arguments of a single call to the library routine.
