14*c5c4113dSnw141292#
15*c5c4113dSnw141292# 1. Trigger execution order tests.
16*c5c4113dSnw141292# These tests ensure that BEFORE and AFTER triggers are fired at the correct
17*c5c4113dSnw141292# times relative to each other and the triggering statement.

19*c5c4113dSnw141292# trigger2-1.1.*: ON UPDATE trigger execution model.
20*c5c4113dSnw141292# trigger2-1.2.*: DELETE trigger execution model.
21*c5c4113dSnw141292# trigger2-1.3.*: INSERT trigger execution model.
22*c5c4113dSnw141292#
23*c5c4113dSnw141292# 2. Trigger program execution tests.
24*c5c4113dSnw141292# These tests ensure that trigger programs execute correctly (ie. that a
25*c5c4113dSnw141292# trigger program can correctly execute INSERT, UPDATE, DELETE * SELECT

28*c5c4113dSnw141292# 3. Selective trigger execution
29*c5c4113dSnw141292# This tests that conditional triggers (ie. UPDATE OF triggers and triggers
30*c5c4113dSnw141292# with WHEN clauses) are fired only fired when they are supposed to be.

37*c5c4113dSnw141292# trigger-program is never executed recursively.

44*c5c4113dSnw141292# of the "count changes" interface.
