# 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. |
