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. |
