# Tests for the update-hook.
#
# 4.1.* - Very simple tests. Test that the update hook is invoked correctly
# for INSERT, DELETE and UPDATE statements, including DELETE
# statements with no WHERE clause.
# 4.2.* - Check that the update-hook is invoked for rows modified by trigger
# bodies. Also that the database name is correctly reported when
# an attached database is modified.
# 4.3.* - Do some sorting, grouping, compound queries, population and
# depopulation of indices, to make sure the update-hook is not
# invoked incorrectly.
#
# EVIDENCE-OF: R-21999-45122 The sqlite3_update_hook() interface
