#
# 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.
