I was looking for a way to create a trigger that would insert the same row into two tables with the same values.

For example, a new row is inserted into pushNotificationQueue as soon as that is inserted, I would like that same exact row to be inserted into messages.

I tried this

CREATE TRIGGER add_to_messages
after insert on mbb_pushNotificationQueue
FOR EACH ROW
insert into mbb_messages select * from mbb_pushNotificationQueue

the only problem with that is that it goes through and adds entries that have already been previously added.
