# Tests to make sure that value returned by last_insert_rowid() (LIRID)
# is updated properly, especially inside triggers
#
# Note 1: insert into table is now the only statement which changes LIRID
# Note 2: upon entry into before or instead of triggers,
# LIRID is unchanged (rather than -1)
# Note 3: LIRID is changed within the context of a trigger,
# but is restored once the trigger exits
# Note 4: LIRID is not changed by an insert into a view (since everything
# is done within instead of trigger context)
