Can I launch a trigger on select statement in mysql?
Nope - you can't trigger on SELECT - you'll have to create a stored procedure (or any other type of logging facility - like a log file or what ever) that you implicitly call on any query statement - easier if you create a wrapper that calls your query, calls the logging and returns query results.
Short answer is No. Triggers are triggered with INSERT
, UPDATE
or DELETE
.
Possible solution for this. rather rare scenario:
- First, write some stored procedures
that do the
SELECT
s you want on table X. - Then, restrict all users to use only
these stored procedures and do not
allow them to directly use
SELECT
on table X. - Then alter the stored procedures to
also call a stored procedure that
performs the action you want
(
INSERT
or whatever).
