being updated, and not some common-table expression that happens to have the

Only this new opcode, and not OP_ResultRow, checks for foreign key errors.
Faster performance, and now also works with RETURNING.

it is slower.

be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have
been processed. This obviates the need for the WHERE_SEEK_TABLE and
WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing
complication, and it allows the covering index optimization to be used
further into WHERE clause processing.

cycles. Might as well leave it off.

interface to the query planner. The UPDATE implementation adds an
OP_FinishSeek before running the final OP_Insert if one is needed.

the one-pass optimization might cause the table seek to be omitted before
reaching row DELETE/INSERT. Fix this by coding an extra OP_Column in that
circumstance. Ticket [ec8abb025e78f40c]
