sl@0
|
14 |
# and UPDATE statement are only evaluated once. See ticket #980.
|
|

|
15 |
# If an expression uses a function that has side-effects or which
|
|
sl@0
|
16 |
# is not deterministic (ex: random()) then we want to make sure
|
|
sl@0
|
17 |
# that the same evaluation occurs for the actual INSERT/UPDATE and
|
|
sl@0
|
18 |
# for the NEW.* fields of any triggers that fire.
