Re: substring ..

Hehe, here is my tests with this:

ctntest2=# SELECT create_date FROM users;
create_date
------------------------
2000-08-29 13:01:53-04
2000-08-27 20:04:41-04
2000-08-27 21:24:28-04
2000-08-30 09:51:16-04
2000-07-25 23:14:08-04
2000-07-25 23:14:08-04
2000-09-01 02:53:02-04
2000-07-25 23:14:08-04
(8 rows)

ctntest2=# SELECT substr(create_date,1,10) FROM users;
substr
------------
2000-08-29
2000-08-27
2000-08-27
2000-08-30
2000-07-25
2000-07-25
2000-09-01
2000-07-25
(8 rows)

ctntest2=# SELECT create_date FROM users WHERE substr(create_date,1,7) =
'2000-08';
create_date
------------------------
2000-08-29 13:01:53-04
2000-08-27 20:04:41-04
2000-08-27 21:24:28-04
2000-08-30 09:51:16-04
(4 rows)

Seems to work fine. My fields are TIMESTAMP. If you really still have
trouble, then try a cast: substr(datefoo::TEXT,1,10) ??
