I am trying to code a trigger that affects two tables at once. Changing the value on a different table is giving me no problem, so I will exclude that from all of my explanations for the sake of brevity. But when I tried it the trigger would not be created. I think you cannot use triggers for the operation you are trying to perform. You cannot have a trigger perform a data manipulation on entries from the same table on which the trigger is fired from. Looking through your code it is not clear what you are trying to achieve?
It should be possible to circumvent this limitation in Mysql, by calling a stored procedure that does the actual update. I really need some help with this Here is an example:. This Trigger should do the trick. I am afraid I have no idea of such Trigger behavior for another issue which you have discovered. Thanks for the help with the insert Update issue. That works well- I couldn't figure out how to get it to do that. I think it would be similar to the first part of the trigger but running on Update.
Problem is I keep getting 'Nested' error messages when I try to update the same table I'm running an Update trigger on. I think once I get the fundamentals worked out like in this issue the Triggers will make a lot more sense. Thanks very much for your help on this, I really appreciate it. I am afraid that you cannot use Update block with the same table as the one on which you have built Trigger Action with event "update" because it will create an infinitive loop of Trigger execution.
That's what I'd thought. So to be clear, if a record is updated in a table it's impossible to update another field in that record OR other records in the same table?
