Hi
I see this article about DB2
http://www-106.ibm.com/developerworks/db2/library/techarticle/dm -0411rielau/?ca=dgr-lnxw06SQL-Speed
The listing 2 example: 1 SELECT D_TAX, D_NEXT_O_ID 2 INTO :dist_tax , :next_o_id 3 FROM OLD TABLE ( UPDATE DISTRICT 4 SET D_NEXT_O_ID = D_NEXT_O_ID + 1 5 WHERE D_W_ID = :w_id 6 AND D_ID = :d_id 7 ) AS OT
I am not a expert in Rule System.
But I ad a look to
http://www.postgresql.org/docs/7.4/static/rules-update.html
And it seems possible in PostgreSQL to build non standard SQL query to do thing like listing 2.
I would like to know from an "expert" of PostgreSQL if such query is really a new stuff to DB2 as the artcile states ? or if PostgreSQL has already the same type of power ?
Cordialement, Jean-Gérard Pailloncy
