| 17:08 | Change the interface to sqlite3GenerateConstraintChecks() for improved lucidity and to fix issues in dealing with UPDATEs for WITHOUT ROWID tables. Make sure iDataCur and iIdxCur are initialized when processing DELETEs of a VIEW. UPDATE processing distinguishes between changes to ROWID and PRIMARY KEY.
