Hi everyone,
Currently we have a policy that prohibit our customers from
creating stored procedures and triggers on their DB's which I
imagine must be driving them up the walls. It's like having a car
with a boot but you are not able to use it. :)
Are there any reasons why we would'nt want customers to make use of
these built in features and what other means are available.
My reading showed that you need the create routine privilege and
you *may* require the super privilege if you have binary logging
enabled (and then that only becomes a potential issue if you are
actually replaying those logs (ie. either for replication or for
media recovery).
I think I was reading the MySQL 5.1 manual - so maybe this is
different with 5.0?
In MySQL 5.0 (I get the impression that's the version you are
running) it requires SUPER to create triggers, however in 5.1 a new
TRIGGER privilege was introduced for that.
The requirement on SUPER for binary logging applies is the
log_bin_trust_function_creators is not set to 1. The reason for this
is to avoid random users creating non-deterministic procedures that
then replicate to a slave and causes the slave and master to get out
of sync. If binary logging is not enabled, SUPER is never required in
order to create a stored procedure. See more in http://dev.mysql.com/
doc/refman/5.0/en/stored-programs-logging.html for MySQL 5.0 or
http://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html
for MySQL 5.1.
Best regards,
Jesper
