Hi all,
I am having some issues with my replication setup which I have narrowed down
to being a problem on the master, more specifically an issue with the binlog
when using a trigger.
I have a trigger on one of my tables that archives an entry before deleting
it:
DELIMITER //
CREATE TRIGGER
Going back to the OP's problem - the original issue I believe was he was
using "old" instead of "OLD" (case-sensitive) - now that's sorted, MySQL
is complaining about a syntax error toward the end of the function
declaration.
I'm surprised by the case sensitivity of OLD though, it works fine
I think you are missing the point. Where is 'OLD' or 'old' defined?
Before you try to imbed it in a trigger, try the basic query. That seems
to be what its complaining about.
OLD is a virtual table which is only present in a trigger - it's like a

Why on earth would you go sending a "unixtime" to the server and then using
a trigger
to convert it into a "real date"?!
