-# This file implements regression tests for SQLite library. Specifically,
-# it tests some compiler optimizations for SQL statements featuring
-# triggers:
-#
-#
-#
-
-# trigger9-1.* -   Test that if there are no references to OLD.* cols, or a
-#                  reference to only OLD.rowid, the data is not loaded.
-#
-# trigger9-2.* -   Test that for NEW.* records populated by UPDATE 
-#                  statements, unused fields are populated with NULL values. 
-#
-# trigger9-3.* -   Test that the temporary tables used for OLD.* references
-#                  in "INSTEAD OF" triggers have NULL values in unused 
-#                  fields.
