**       N

** occurs before the start of each row.  N means a NULL value.
** I mean an 8-byte little-endian integer <int>.  F is a floating point
** number with an 8-byte little-endian IEEE floating point value <ieee-float>.
** B means blobs of <size> bytes.  T means text rendered as <size>
** bytes of UTF-8.  The <n> and <size> values are expressed as an ASCII
** text integers.
**
** For each SQL statement in the X input, there is one S segment.  Each
** S segment is followed by zero or more R segments, one for each row in the
** result set.  After each R, there are one or more N, I, F, B, or T segments,

** integer key called the [ROWID | "rowid"]. ^The rowid is always available
** as an undeclared column named ROWID, OID, or _ROWID_ as long as those
** names are not also used by explicitly declared columns. ^If
** the table has a column of type [INTEGER PRIMARY KEY] then that column
** is another alias for the rowid.
**
** ^The sqlite3_last_insert_rowid(D) interface usually returns the [rowid] of
** the most recent successful [INSERT] into a rowid table or [virtual table]

** on database connection D. ^Inserts into [WITHOUT ROWID] tables are not
** recorded. ^If no successful [INSERT]s into rowid tables have ever occurred 
** on the database connection D, then sqlite3_last_insert_rowid(D) returns 
** zero.
**
** As well as being set automatically as rows are inserted into database
** tables, the value returned by this function may be set explicitly by
** [sqlite3_set_last_insert_rowid()]
**
** Some virtual table implementations may INSERT rows into rowid tables as
** part of committing a transaction (e.g. to flush data accumulated in memory
** to disk). In this case subsequent calls to this function return the rowid
** associated with these internal INSERT operations, which leads to 
** unintuitive results. Virtual table implementations that do write to rowid
** tables in this way can avoid this problem by restoring the original 
** rowid value using [sqlite3_set_last_insert_rowid()] before returning 
** control to the user.
**
** ^(If an [INSERT] occurs within a trigger then this routine will 
** return the [rowid] of the inserted row as long as the trigger is 


** running. Once the trigger program ends, the value returned 
** by this routine reverts to what it was before the trigger was fired.)^

**
** ^An [INSERT] that fails due to a constraint violation is not a
** successful [INSERT] and does not change the value returned by this
** routine.  ^Thus INSERT OR FAIL, INSERT OR IGNORE, INSERT OR ROLLBACK,
** and INSERT OR ABORT make no changes to the return value of this
** routine when their insertion fails.  ^(When INSERT OR REPLACE
** encounters a constraint violation, it does not fail.  The
................................................................................
** function is running and thus changes the last insert [rowid],
** then the value returned by [sqlite3_last_insert_rowid()] is
** unpredictable and might not equal either the old or the new
** last insert [rowid].

  **  PRAGMA optimize
  **  PRAGMA optimize(MASK)
  **  PRAGMA schema.optimize
  **  PRAGMA schema.optimize(MASK)
  **
  ** Attempt to optimize the database.  All schemas are optimized in the first
  ** two forms, and only the specified schema is optimized in the latter two.
  **
  ** The details of optimizations performed by this pragma are expected
  ** to change and improve over time.  Applications should anticipate that
  ** this pragma will perform new optimizations in future releases.
  **
  ** The optional argument is a bitmask of optimizations to perform:
  **
  **    0x0001    Debugging mode.  Do not actually perform any optimizations
  **              but instead return one line of text for each optimization
  **              that would have been done.  Off by default.
  **
  **    0x0002    Run ANALYZE on tables that might benefit.  On by default.
  **              See below for additional information.
  **
  **    0x0004    (Not yet implemented) Record usage and performance 
  **              information from the current session in the
  **              database file so that it will be available to "optimize"
  **              pragmas run by future database connections.
  **
  **    0x0008    (Not yet implemented) Create indexes that might have
  **              been helpful to recent queries
  **
  ** The default MASK is and always shall be 0xfffe.  0xfffe means perform all    ** of the optimizations listed above except Debug Mode, including new
  ** optimizations that have not yet been invented.  If new optimizations are
  ** ever added that should be off by default, those off-by-default 
  ** optimizations will have bitmasks of 0x10000 or larger.
  **
  ** DETERMINATION OF WHEN TO RUN ANALYZE
  **
  ** In the current implementation, a table is analyzed if only if all of
  ** the following are true:
  **
  ** (1) MASK bit 0x02 is set.
  **
  ** (2) The query planner used sqlite_stat1-style statistics for one or
  **     more indexes of the table at some point during the lifetime of
  **     the current connection.
  **
  ** (3) One or more indexes of the table are currently unanalyzed OR
  **     the number of rows in the table has increased by 25 times or more
  **     since the last time ANALYZE was run.
  **
  ** The rules for when tables are analyzed are likely to change in
  ** future releases.
