How do I get the time when a mysql trigger was created or updated?
advertisements
We have a trigger in our mysql database which on update affect some data in database. But for some calculation we need to know when this trigger was first created and when it was updated last. Is it possible to get this data from information_schema or any where else?
Unfortunately the answer is no. There is a column CREATED in the schema for triggers, but it is unused (always NULL) at the present time:
The following columns currently always contain NULL: TRIGGER_CATALOG, EVENT_OBJECT_CATALOG, ACTION_CONDITION, ACTION_REFERENCE_OLD_TABLE, ACTION_REFERENCE_NEW_TABLE, and CREATED.
