table1 table1_removed
anotherTable
create or replace RULE rec_remove as ON DELETE TO table1 do insert into table1_remove select old.*, a.acc from old g join anotherTable a on g.acc=a.other_acc; === the parser complained ERROR: relation "*OLD*" does not exist So I used select old.*, a.acc from table1 g join anotherTable a on g.acc=a.other_acc;
This worked find.
When I run delete on table1, 213 rows.
tmp table received 213X213 = 45369 rows. each row is duplicated 213 times.
My question: Is it possible to bring in another table in a rule? Where am I wrong in this case. Certainly I don't want that duplications.
My table1_removed contain a primary key for the id. The speed of doing the delete is also very slow
apparently it has to do N-square inserts.
I have very limited information to read on the manual of postgres.
Any solution?
