Hi,
Could anyone please let me know how to perform the following in postgresql
I have two tables called P , Q with the same attributes and data tpyes. I want to insert a record ( for example called A) into table P, when deleting the same record( for example called A which is already in the other table) from the other table Q.
Thank you
arun

Pretty straight ahead. You can either use a fancy trigger setup, or just
do it in a transaction to ensure integrity:
begin;
insert into P (select * from Q where recid='A';
delete from Q where recid='A';
commit;
If the insert fails, the delete won't happen either.
That close to what you want?
