Thread: 7.2 date/time format function problems

7.2 date/time format function problems

From
Nicholas Barthelemy
Date:
I have just installed redhat 8.0. It comes with postgresql rpms for 
7.2.2. I have been trying to get an
application I have written to work, but my queries fail whenever I have 
queries that use internal
date/time formatting functions.
example:

SELECT a.assignmentid AS "id",
u.lastname || ', ' || u.firstname || ' ' || u.middleint AS "assigned",
j.name AS "job_name",
extract(DOW FROM TIMESTAMP TIMESTAMP(a.startdate)) AS "dow",
TO_CHAR(TO_TIMESTAMP(a.starttime, 'HH:MI:SS'), 'HH12:MI am') AS 
"starttime",
TO_CHAR(TO_TIMESTAMP(a.stoptime, 'HH:MI:SS'), 'HH12:MI am') AS "stoptime",
((extract(HOUR FROM TIME (a.stoptime - a.starttime)) + (extract(MINUTE FROM TIME (a.stoptime - a.starttime))/60)) -
a.break)
 
AS "hrs",
a.break AS "break"
FROM assignment a LEFT JOIN users u USING(userid),
schedule s, job j, account ac, location l, groups g
WHERE s.scheduleid = 1 AND
s.scheduleid = a.scheduleid AND
s.accountid = 3 AND
s.accountid = ac.accountid AND
s.locationid = 1 AND
s.locationid = l.locationid AND
s.groupid = g.groupid AND
s.scheduleid = s.scheduleid AND
a.jobid = j.jobid
ORDER BY j.name ASC, a.starttime ASC, u.lastname ASC;

ERROR:  parser: parse error at or near "TIMESTAMP"

The problem areas are the timestamp() and extract(hour from time) 
functions. If anyone would
be so kind as to help me with this issue, it would be greatly 
appreciated. I don't know if I have to
enable something for these functions to work or if the format changed 
for 7.2.2. I checked the
documentation and it was exactly like 7.1.

Thanks for your help,
Nicholas

timestamp() and time() became the type specifiers for the type with
a particular precision.  You can use "timestamp"() or "time"() or
it'd probably be better to use SQL standard casts, CAST (expr AS type).

Oooh.  Looks like TIMESTAMP became a reserved keyword.
