UPDaTE JOINED TABLES

UPDaTE JOINED TABLES

(OP)
Hello..

Will this work :

CODE

UPDATE POPORL
  SET POPORL.EXPARRIVAL = 20100418
  FROM POPORH1  POPORL
 WHERE POPORL.PORHSEQ=POPORH1.PORHSEQ
   AND POPORH1.PONUMBER="004386"

RE: UPDaTE JOINED TABLES

I think it should.  It'll probably depend on the version of PSQL you are using.  Here's an example from the PSQL documentation:

CODE

CREATE table t1 (c1 integer, c2 integer)
INSERT INTO t1 VALUES (0, 10)
INSERT INTO t1 VALUES (0, 10)
INSERT INTO t1 VALUES (2, 20)
INSERT INTO t1 VALUES (2, 20)
DROP table t2
CREATE table t2 (c1 integer, c2 integer)
INSERT INTO t2 VALUES (2, 20)
INSERT INTO t2 VALUES (2, 20)
INSERT INTO t2 VALUES (3, 30)
INSERT INTO t2 VALUES (3, 30)
UPDATE t1 SET t1.c1 = 1 FROM t2 WHERE t1.c2 = t2.c2

Thank You Mirtheil :),
This seem to do the trick without killing the tables...:

CODE

UPDATE POPORL SET POPORL.EXPARRIVAL = 20100418
  FROM POPORH1
WHERE POPORL.PORHSEQ=POPORH1.PORHSEQ
AND POPORH1.PONUMBER='004386'
