I have postgres installed in my machine and have a simple task to do.
Step1) Fetch all the tables in the Database with name staerting with "AA"
Step2) On each table you get fire a simple SQL query:
select * from <tablename>;
Step3) Right these into a flat file.
I have to carry out all these steps using a prcedure/function.
The function would be called by a trigger. Now i need to know how to make a postgres function for that.
My problem: My experience with database is almost 5 days and I can't seem to understand the documentation, like how to catch the return value. How to run the procedure for testing without firing the trigger. So could anyone help me with that.
