//	** one.  Each row extracted from Queue is output to pDest.  Then the single

//	** If the query has an ORDER BY, then entries in the Queue table are kept in

//	**
//	** If a LIMIT clause is provided, then the iteration stops after LIMIT rows

//	**
//	**     0x01      Canonical RFC-8259 JSON text
//	**     0x02      JSON text with optional JSON-5 extensions
//	**     0x04      Superficially appears to be JSONB
//	**     0x08      Strictly well-formed JSONB
//	**
//	** If the FLAGS argument is omitted, it defaults to 1.  Useful values for
//	** FLAGS include:
//	**
//	**    1          Strict canonical JSON text
//	**    2          JSON text perhaps with JSON-5 extensions
//	**    4          Superficially appears to be JSONB
//	**    5          Canonical JSON text or superficial JSONB
//	**    6          JSON-5 text or superficial JSONB
//	**    8          Strict JSONB
//	**    9          Canonical JSON text or strict JSONB
//	**    10         JSON-5 text or strict JSONB
//	**
//	** Other flag combinations are redundant.  For example, every canonical
//	** JSON text is also well-formed JSON-5 text, so FLAG values 2 and 3
//	** are the same.  Similarly, any input that passes a strict JSONB validation
//	** will also pass the superficial validation so 12 through 15 are the same
//	** as 8 through 11 respectively.
//	**
//	** This routine runs in linear time to validate text and when doing strict
//	** JSONB validation.  Superficial JSONB validation is constant time,
//	** assuming the BLOB is already in memory.  The performance advantage
//	** of superficial JSONB validation is why that option is provided.
//	** Application developers can choose to do fast superficial validation or
//	** slower strict validation, according to their specific needs.
//	**
//	** Only the lower four bits of the FLAGS argument are currently used.
//	** Higher bits are reserved for future expansion.   To facilitate
//	** compatibility, the current implementation raises an error if any bit
//	** in FLAGS is set other than the lower four bits.
//	**
//	** The original circa 2015 implementation of the JSON routines in
//	** SQLite only supported canonical RFC-8259 JSON text and the json_valid()
//	** function only accepted one argument.  That is why the default value
//	** for the FLAGS argument is 1, since FLAGS=1 causes this routine to only
//	** recognize canonical RFC-8259 JSON text as valid.  The extra FLAGS
//	** argument was added when the JSON routines were extended to support
//	** JSON5-like extensions and binary JSONB stored in BLOBs.
//	**
//	** Return Values:
//	**
//	**   *   Raise an error if FLAGS is outside the range of 1 to 15.
//	**   *   Return NULL if the input is NULL
//	**   *   Return 1 if the input is well-formed.

//	/*
//	** Generate code for a compound SELECT statement using a merge
//	** algorithm.  The compound must have an ORDER BY clause for this
//	** to work.
//	**
//	** We assume a query of the following form:
//	**
//	**      <selectA>  <operator>  <selectB>  ORDER BY <orderbylist>
//	**
//	** <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT.  The idea
//	** is to code both <selectA> and <selectB> with the ORDER BY clause as
//	** co-routines.  Then run the co-routines in parallel and merge the results
//	** into the output.  In addition to the two coroutines (called selectA and
//	** selectB) there are 7 subroutines:
//	**
//	**    outA:    Move the output of the selectA coroutine into the output
//	**             of the compound query.
//	**
//	**    outB:    Move the output of the selectB coroutine into the output
//	**             of the compound query.  (Only generated for UNION and
//	**             UNION ALL.  EXCEPT and INTERSECT never output a row that
//	**             appears only in B.)
//	**
//	**    AltB:    Called when there is data from both coroutines and A<B.
//	**
//	**    AeqB:    Called when there is data from both coroutines and A==B.
//	**
//	**    AgtB:    Called when there is data from both coroutines and A>B.
//	**
//	**    EofA:    Called when data is exhausted from selectA.
//	**
//	**    EofB:    Called when data is exhausted from selectB.
//	**
//	** The implementation of the latter five subroutines depend on which
//	** <operator> is used:
//	**
//	**
//	**             UNION ALL         UNION            EXCEPT          INTERSECT
//	**          -------------  -----------------  --------------  -----------------
//	**   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
//	**
//	**   AeqB:   outA, nextA         nextA             nextA         outA, nextA
//	**
//	**   AgtB:   outB, nextB      outB, nextB          nextB            nextB
//	**
//	**   EofA:   outB, nextB      outB, nextB          halt             halt
//	**
//	**   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
//	**
//	** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
//	** causes an immediate jump to EofA and an EOF on B following nextB causes
//	** an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
//	** following nextX causes a jump to the end of the select processing.
//	**
//	** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
//	** within the output subroutine.  The regPrev register set holds the previously
//	** output value.  A comparison is made against this value and the output
//	** is skipped if the next results would be the same as the previous.
//	**
//	** The implementation plan is to implement the two coroutines and seven
//	** subroutines first, then put the control logic at the bottom.  Like this:
//	**
//	**          goto Init
//	**     coA: coroutine for left query (A)
//	**     coB: coroutine for right query (B)
//	**    outA: output one row of A
//	**    outB: output one row of B (UNION and UNION ALL only)
//	**    EofA: ...
//	**    EofB: ...
//	**    AltB: ...
//	**    AeqB: ...
//	**    AgtB: ...
//	**    Init: initialize coroutine registers
//	**          yield coA, on eof goto EofA
//	**          yield coB, on eof goto EofB
//	**    Cmpr: Compare A, B
//	**          Jump AltB, AeqB, AgtB
//	**     End: ...
//	**
//	** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
//	** actually called using Gosub and they do not Return.  EofA and EofB loop
//	** until all data is exhausted then jump to the "end" label.  AltB, AeqB,
//	** and AgtB jump to either Cmpr or to one of EofA or EofB.

//	**
//	**       c) for leaf nodes, that there is an entry in the %_rowid

//	**
//	**   2. That there are the same number of entries in the %_rowid table

//	** The PRAGMA short_column_names and PRAGMA full_column_names settings are
//	** deprecated.  The default setting is short=ON, full=OFF.  99.9% of all

//	** other modes for legacy:
//	**
//	**    short=OFF, full=OFF:      Column name is the text of the expression has it
//	**                              originally appears in the SELECT statement.  In
//	**                              other words, the zSpan of the result expression.
//	**
//	**    short=ON, full=OFF:       (This is the default setting).  If the result

//	**                              result column name is just the table column
//	**                              name: COLUMN.  Otherwise use zSpan.
//	**

//	** Generate code to do constraint checks prior to an INSERT or an UPDATE

//	**
//	** The regNewData parameter is the first register in a range that contains
//	** the data to be inserted or the data after the update.  There will be
//	** pTab->nCol+1 registers in this range.  The first register (the one
//	** that regNewData points to) will contain the new rowid, or NULL in the
//	** case of a WITHOUT ROWID table.  The second register in the range will
//	** contain the content of the first table column.  The third register will
//	** contain the content of the second table column.  And so forth.
//	**
//	** The regOldData parameter is similar to regNewData except that it contains
//	** the data prior to an UPDATE rather than afterwards.  regOldData is zero
//	** for an INSERT.  This routine can distinguish between UPDATE and INSERT by
//	** checking regOldData for zero.
//	**
//	** For an UPDATE, the pkChng boolean is true if the true primary key (the
//	** rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
//	** might be modified by the UPDATE.  If pkChng is false, then the key of
//	** the iDataCur content table is guaranteed to be unchanged by the UPDATE.
//	**
//	** For an INSERT, the pkChng boolean indicates whether or not the rowid
//	** was explicitly specified as part of the INSERT statement.  If pkChng
//	** is zero, it means that the either rowid is computed automatically or
//	** that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
//	** pkChng will only be true if the INSERT statement provides an integer
//	** value for either the rowid column or its INTEGER PRIMARY KEY alias.
//	**
//	** The code generated by this routine will store new index entries into
//	** registers identified by aRegIdx[].  No index entry is created for
//	** indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
//	** the same as the order of indices on the linked list of indices
//	** at pTab->pIndex.
//	**
//	** (2019-05-07) The generated code also creates a new record for the
//	** main table, if pTab is a rowid table, and stores that record in the
//	** register identified by aRegIdx[nIdx] - in other words in the first
//	** entry of aRegIdx[] past the last index.  It is important that the
//	** record be generated during constraint checks to avoid affinity changes
//	** to the register content that occur after constraint checks but before
//	** the new record is inserted.
//	**
//	** The caller must have already opened writeable cursors on the main
//	** table and all applicable indices (that is to say, all indices for which
//	** aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
//	** inserting or updating a rowid table, or the cursor for the PRIMARY KEY
//	** index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor
//	** for the first index in the pTab->pIndex list.  Cursors for other indices
//	** are at iIdxCur+N for the N-th element of the pTab->pIndex list.
//	**
//	** This routine also generates code to check constraints.  NOT NULL,
//	** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
//	** then the appropriate action is performed.  There are five possible
//	** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
//	**
//	**  Constraint type  Action       What Happens
//	**  ---------------  ----------   ----------------------------------------
//	**  any              ROLLBACK     The current transaction is rolled back and
//	**                                sqlite3_step() returns immediately with a
//	**                                return code of SQLITE_CONSTRAINT.
//	**

//	**
//	**   2.  Read/write cursors for all indices of pTab must be open as
//	**       cursor number iIdxCur+i for the i-th index.
//	**
//	**   3.  The primary key for the row to be deleted must be stored in a
//	**       sequence of nPk memory cells starting at iPk.  If nPk==0 that means
//	**       that a search record formed from OP_MakeRecord is contained in the
//	**       single memory location iPk.
//	**
//	** eMode:
//	**   Parameter eMode may be passed either ONEPASS_OFF (0), ONEPASS_SINGLE, or
//	**   ONEPASS_MULTI.  If eMode is not ONEPASS_OFF, then the cursor
//	**   iDataCur already points to the row to delete. If eMode is ONEPASS_OFF
//	**   then this function must seek iDataCur to the entry identified by iPk
//	**   and nPk before reading from it.
//	**
//	**   If eMode is ONEPASS_MULTI, then this call is being made as part
//	**   of a ONEPASS delete that affects multiple rows. In this case, if
//	**   iIdxNoSeek is a valid cursor number (>=0) and is not the same as
//	**   iDataCur, then its position should be preserved following the delete
//	**   operation. Or, if iIdxNoSeek is not a valid cursor number, the
//	**   position of iDataCur should be preserved instead.
//	**
//	** iIdxNoSeek:
//	**   If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,
//	**   then it identifies an index cursor (from within array of cursors
//	**   starting at iIdxCur) that already points to the index entry to be deleted.
//	**   Except, this optimization is disabled if there are BEFORE triggers since
//	**   the trigger body might have moved the cursor.

//	** This routine is called to handle SQL of the following forms:
//	**
//	**    insert into TABLE (IDLIST) values(EXPRLIST),(EXPRLIST),...
//	**    insert into TABLE (IDLIST) select
//	**    insert into TABLE (IDLIST) default values
//	**
//	** The IDLIST following the table name is always optional.  If omitted,
//	** then a list of all (non-hidden) columns for the table is substituted.
//	** The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
//	** is omitted.
//	**
//	** For the pSelect parameter holds the values to be inserted for the
//	** first two forms shown above.  A VALUES clause is really just short-hand
//	** for a SELECT statement that omits the FROM clause and everything else
//	** that follows.  If the pSelect parameter is NULL, that means that the
//	** DEFAULT VALUES form of the INSERT statement is intended.
//	**
//	** The code generated follows one of four templates.  For a simple
//	** insert with data coming from a single-row VALUES clause, the code executes
//	** once straight down through.  Pseudo-code follows (we call this
//	** the "1st template"):
//	**
//	**         open write cursor to <table> and its indices
//	**         put VALUES clause expressions into registers
//	**         write the resulting record into <table>
//	**         cleanup
//	**
//	** The three remaining templates assume the statement is of the form
//	**
//	**   INSERT INTO <table> SELECT ...
//	**
//	** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
//	** in other words if the SELECT pulls all columns from a single table
//	** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
//	** if <table2> and <table1> are distinct tables but have identical
//	** schemas, including all the same indices, then a special optimization
//	** is invoked that copies raw records from <table2> over to <table1>.
//	** See the xferOptimization() function for the implementation of this
//	** template.  This is the 2nd template.
//	**
//	**         open a write cursor to <table>
//	**         open read cursor on <table2>
//	**         transfer all records in <table2> over to <table>
//	**         close cursors
//	**         foreach index on <table>
//	**           open a write cursor on the <table> index
//	**           open a read cursor on the corresponding <table2> index
//	**           transfer all records from the read to the write cursors
//	**           close cursors
//	**         end foreach
//	**
//	** The 3rd template is for when the second template does not apply
//	** and the SELECT clause does not read from <table> at any time.
//	** The generated code follows this template:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the rows in the SELECT
//	**           load values into registers R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end-coroutine X
//	**      B: open write cursor to <table> and its indices
//	**      C: yield X, at EOF goto D
//	**         insert the select result into <table> from R..R+n
//	**         goto C
//	**      D: cleanup
//	**
//	** The 4th template is used if the insert statement takes its
//	** values from a SELECT but the data is being inserted into a table
//	** that is also read as part of the SELECT.  In the third form,
//	** we have to use an intermediate table to store the results of
//	** the select.  The template is like this:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the tables in the SELECT
//	**           load value into register R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end co-routine R
//	**      B: open temp table
//	**      L: yield X, at EOF goto M
//	**         insert row from R..R+n into temp table
//	**         goto L
//	**      M: open write cursor to <table> and its indices
//	**         rewind temp table
//	**      C: loop over rows of intermediate table
//	**           transfer values form intermediate table into <table>
//	**         end loop
//	**      D: cleanup
