** The sqlite.lastRowid records the last insert rowid generated by an
** insert statement. Inserts on views do not affect its value. Each
** trigger has its own context, so that lastRowid can be updated inside
** triggers as usual. The previous value will be restored once the trigger
** exits. Upon entering a before or instead of trigger, lastRowid is no
** longer (since after version 2.8.12) reset to -1.
**
** The sqlite.nChange does not count changes within triggers and keeps no
** context. It is reset at start of sqlite_exec.
** The sqlite.lsChange represents the number of changes made by the last
** insert, update, or delete statement. It remains constant throughout the
** length of a statement and is then updated by OP_SetCounts. It keeps a
** context stack just like lastRowid so that the count of changes
** within a trigger is not seen outside the trigger. Changes to views do not
** affect the value of lsChange.
** The sqlite.csChange keeps track of the number of current changes (since
** the last statement) and is used to update sqlite_lsChange.
