# 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
