RE: [SQL] Problems with default date and time

sorry, Here's the create statement.

CREATE TABLE "orders" (
"ord_id" int4 DEFAULT nextval ( 'next_ord_id' ) NOT NULL,
"req_id" int4 DEFAULT nextval ( 'next_req_id' ) NOT NULL,
"ord_description" character varying(1500),
"ord_priority" character varying(1500),
"ord_pri_order" int4,
"ord_time" time DEFAULT now(),
"ord_date" date DEFAULT now(),
"ord_timestamp" datetime DEFAULT now(),
"ord_tech" character varying(1500),
"ord_stat" character varying(2),
"ord_notes" character varying(1500),
"ord_whse" int4);

The time and date fields are for reporting purposes while the timestamp is
for calculating elapsed time, so I need all of them. When I make those
changes, I get:

ERROR: DEFAULT clause type 'timestamp' mismatched with column type 'time'

You should not use 'now'. It will be replaced with the current time.
Instead use now() and remove "text".

Also, I'd skip the time and date fields and exchange timestamp with
datetime. You would still be able to get the date and time from the
ord_timestamp field using:

select ord_timestamp::time, ord_timestamp::date from tablename;

The reason I'd use datetime instead of datetime is because you
can't cast from timestamp to time (afaik).

Hope this helps.
