+# This file implements regression tests for SQLite library.

+# This file implements tests to make sure expression of an INSERT
+# and UPDATE statement are only evaluated once.  See ticket #980.
+# If an expression uses a function that has side-effects or which
+# is not deterministic (ex: random()) then we want to make sure
+# that the same evaluation occurs for the actual INSERT/UPDATE and
+# for the NEW.* fields of any triggers that fire.
