Hi, Brian! On Aug 16, Brian Evans wrote:
I have an issue where a fast triggering event, running every 30 seconds, is occasionally running multiple times without each finishing. This is causing duplicate data as things are marked done one at a time.
I am trying to figure a solution such that this event can only run singly, but what is the best way? DISABLE at start and ENABLE at end?
That would work, I suppose. Alternatively you can use GET_LOCK to synchronize events.
Do SESSION variables work between event invocations?
I'm not sure I understand this. You mean user variables, like @foo? No, every invocation is executed as in a new connection (kind of, not really a new connection) and user variables dissapear at disconnect. Regards, Sergei
