| 11 | # This file implements regression tests for SQLite library. |
||
| 12 | # |
||
| 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. |
