| 13 # This file implements tests to make sure expression of an INSERT |
| 14 # and UPDATE statement are only evaluated once. See ticket #980. |
| 15 # If an expression uses a function that has side-effects or which |
| 16 # is not deterministic (ex: random()) then we want to make sure |
| 17 # that the same evaluation occurs for the actual INSERT/UPDATE and |
| 18 # for the NEW.* fields of any triggers that fire. |
