-** when the database connection has [PRAGMA synchronous] set to OFF.)^

-** opcode as doing so may disrupt the operation of the specialized VFSes
-** that do require it.
+** No longer in use.
+**
+** <li>[[SQLITE_FCNTL_SYNC]]
+** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
+** sent to the VFS immediately before the xSync method is invoked on a
+** database file descriptor. Or, if the xSync method is not invoked
+** because the user has configured SQLite with
+** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
+** of the xSync method. In most cases, the pointer argument passed with
+** this file-control is NULL. However, if the database file is being synced
+** as part of a multi-database commit, the argument points to a nul-terminated
+** string containing the transactions master-journal file name. VFSes that
+** do not need this signal should silently ignore this opcode. Applications
+** should not call [sqlite3_file_control()] with this opcode as doing so may
+** disrupt the operation of the specialized VFSes that do require it.
+**
+** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
+** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
+** and sent to the VFS after a transaction has been committed immediately
+** but before the database is unlocked. VFSes that do not need this signal
+** should silently ignore this opcode. Applications should not call
+** [sqlite3_file_control()] with this opcode as doing so may disrupt the
+** operation of the specialized VFSes that do require it.
**
** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
** SQLite stack may generate instances of this file control if
** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
**
+** <li>[[SQLITE_FCNTL_HAS_MOVED]]
+** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
+** pointer to an integer and it writes a boolean into that integer depending
+** on whether or not the file has been renamed, moved, or deleted since it
+** was first opened.
+**
+** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging. This
+** opcode causes the xFileControl method to swap the file handle with the one

+** <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter

+** processes uses nolock=1.
+**
+** <li> <b>immutable</b>: ^The immutable parameter is a boolean query

+** The results of a SELECT can be distributed in several ways, as defined
+** by one of the following macros. The "SRT" prefix means "SELECT Result
+** Type".
+**
+** SRT_Union Store results as a key in a temporary index
+** identified by pDest->iSDParm.
+**
+** SRT_Except Remove results from the temporary index pDest->iSDParm.
+**
+** SRT_Exists Store a 1 in memory cell pDest->iSDParm if the result
+** set is not empty.
+**
+** SRT_Discard Throw the results away. This is used by SELECT
+** statements within triggers whose only purpose is
+** the side-effects of functions.
+**
+** All of the above are free to ignore their ORDER BY clause. Those that
+** follow must honor the ORDER BY clause.
+**
+** SRT_Output Generate a row of output (using the OP_ResultRow
+** opcode) for each row in the result set.
+**
+** SRT_Mem Only valid if the result is a single column.
+** Store the first column of the first result row
+** in register pDest->iSDParm then abandon the rest
+** of the query. This destination implies "LIMIT 1".
+**
+** SRT_Set The result must be a single column. Store each
+** row of result as the key in table pDest->iSDParm.
+** Apply the affinity pDest->affSdst before storing
+** results. Used to implement "IN (SELECT ...)".
+**
+** SRT_EphemTab Create an temporary table pDest->iSDParm and store
+** the result there. The cursor is left open after
+** returning. This is like SRT_Table except that
+** this destination uses OP_OpenEphemeral to create
+** the table first.
+**
+** SRT_Coroutine Generate a co-routine that returns a new row of
+** results each time it is invoked. The entry point
+** of the co-routine is stored in register pDest->iSDParm
+** and the result row is stored in pDest->nDest registers
+** starting with pDest->iSdst.
+**
+** SRT_Table Store results in temporary table pDest->iSDParm.
+** SRT_Fifo This is like SRT_EphemTab except that the table
+** is assumed to already be open. SRT_Fifo has
+** the additional property of being able to ignore
+** the ORDER BY clause.
+**
+** SRT_DistFifo Store results in a temporary table pDest->iSDParm.
+** But also use temporary table pDest->iSDParm+1 as
+** a record of all prior results and ignore any duplicate
+** rows. Name means: "Distinct Fifo".
+**
+** SRT_Queue Store results in priority queue pDest->iSDParm (really
+** an index). Append a sequence number so that all entries
+** are distinct.
+**
+** SRT_DistQueue Store results in priority queue pDest->iSDParm only if
+** the same record has never been stored before. The
+** index at pDest->iSDParm+1 hold all prior stores.

-** The code in this file implements execution method of the

-** handles housekeeping details such as creating and deleting
-** VDBE instances. This file is solely interested in executing
-** the VDBE program.
-**
-** In the external interface, an "sqlite3_stmt*" is an opaque pointer
-** to a VDBE.
-**
-** The SQL parser generates a program which is then executed by
-** the VDBE to do the work of the SQL statement. VDBE programs are
-** similar in form to assembly language. The program consists of
-** a linear sequence of operations. Each operation has an opcode
-** and 5 operands. Operands P1, P2, and P3 are integers. Operand P4
-** is a null-terminated string. Operand P5 is an unsigned character.
-** Few opcodes use all 5 operands.
-**
-** Computation results are stored on a set of registers numbered beginning
-** with 1 and going up to Vdbe.nMem. Each register can store
-** either an integer, a null-terminated string, a floating point
-** number, or the SQL "NULL" value. An implicit conversion from one
-** type to the other occurs as necessary.
-**
-** Most of the code in this file is taken up by the sqlite3VdbeExec()
-** function which does the work of interpreting a VDBE program.
-** But other routines are also provided to help in building up
-** a program instruction by instruction.

-** Generate VDBE code that will verify the schema cookie and start

-** It is important that all schema cookies be verified and all
-** read transactions be started before anything else happens in
-** the VDBE program. But this routine can be called after much other
-** code has been generated. So here is what we do:
-**
-** The first time this routine is called, we code an OP_Goto that
-** will jump to a subroutine at the end of the program. Then we
-** record every database that needs its schema verified in the
-** pParse->cookieMask field. Later, after all other code has been
-** generated, the subroutine that does the cookie verifications and
-** starts the transactions will be coded and the OP_Goto P2 value
-** will be made to point to that subroutine. The generation of the
-** cookie verification subroutine code happens in sqlite3FinishCoding().
-**
-** If iDb<0 then code the OP_Goto only - don't set flag to verify the
-** schema on any databases. This can be used to position the OP_Goto
-** early in the code, before we know if any database tables will be used.
+** Record the fact that the schema cookie will need to be verified
+** for database iDb. The code to actually verify the schema cookie
+** will occur at the end of the top-level VDBE and will be generated
+** later, by sqlite3FinishCoding().
