Re: From select to delete - Mailing list pgsql-general

I've got another great advice to use DELETE ... USING
instead of DELETE ... (SUB-SELECT),
so my procedure looks now like this (for archive):

        create or replace function pref_delete_user(_id varchar,
            _reason varchar) returns void as $BODY$
                begin

                create temporary table temp_gids (gid int not null) on
commit drop;
                insert into temp_gids (gid) select gid from
pref_scores where id=_id;

                delete from pref_scores p
                using temp_gids t
                where p.gid = t.gid;

                delete from pref_games p
                using temp_gids t
                where p.gid = t.gid;

                /* more delete's here */

                end;
        $BODY$ language plpgsql;
