I've being working on triggers in mysql lately. I come across this issue that when I want to pass a parameter into the trigger, I cannot find a way to do so. I've read the Mysql some online post that I am not allowed to pass parameters into triggers like store procedures or function.
I wish to know if I still can pass parameters into trigger by other methods beside inserts the value into database first and then uses keyword 'new' or 'old' to get the job done in conjunction with DELETE, UPDATE, and INSERT commands? Thanks.
