|
|
# Regression testing of FOR EACH ROW table triggers on WITHOUT ROWID
|
|
# tables.
|
|
#
|
|
# 1. Trigger execution order tests.
|
|
# These tests ensure that BEFORE and AFTER triggers are fired at the correct
|
|
# times relative to each other and the triggering statement.
|
|
#
|
|
# without_rowid4-1.1.*: ON UPDATE trigger execution model.
|
|
# without_rowid4-1.2.*: DELETE trigger execution model.
|
|
# without_rowid4-1.3.*: INSERT trigger execution model.
|
|
#
|
|
# 2. Trigger program execution tests.
|
|
# These tests ensure that trigger programs execute correctly (ie. that a
|
|
# trigger program can correctly execute INSERT, UPDATE, DELETE * SELECT
|
|
# statements, and combinations thereof).
|
|
#
|
|
# 3. Selective trigger execution
|
|
# This tests that conditional triggers (ie. UPDATE OF triggers and triggers
|
|
# with WHEN clauses) are fired only fired when they are supposed to be.
|
|
#
|
|
# without_rowid4-3.1: UPDATE OF triggers
|
|
# without_rowid4-3.2: WHEN clause
|
|
#
|
|
# 4. Cascaded trigger execution
|
|
# Tests that trigger-programs may cause other triggers to fire. Also that a
|
|
# trigger-program is never executed recursively.
|
|
#
|
|
# without_rowid4-4.1: Trivial cascading trigger
|
|
# without_rowid4-4.2: Trivial recursive trigger handling
|
|
#
|
|
# 5. Count changes behaviour.
|
|
# Verify that rows altered by triggers are not included in the return value
|
|
# of the "count changes" interface.
|
|
#
|
|
# 6. ON CONFLICT clause handling
|
|
# without_rowid4-6.1[a-f]: INSERT statements
|
|
# without_rowid4-6.2[a-f]: UPDATE statements
|
|
#
|
|
# 7. & 8. Triggers on views fire correctly.
