Time Stamp

Question

I am trying to add Time stamp along with the date. But using the TO_CHAR function getting error as Invalid Number.
Please help me to sort out this problem. The query for which I am facing this issue is.
SELECT A.NAME ,A.ounum ,A.divi,A.lastupd
FROM temp A
WHERE A.div ='2.3 xyz'
and A.OUNUM is NOT NULL
AND A.lastupd BETWEEN TO_CHAR('08-DEC-2008 00:00:00','DD-MON-YYYY HH:MI:SS')
AND TO_CHAR(SYSDATE,'DD-MON-YYYY HH:MI:SS')
getting error as Invalid number ORA-01722. Please suggest some solution for this.

Answer 1

SELECT A.NAME ,A.ounum ,A.divi,A.lastupd
FROM temp A
WHERE A.div ='2.3 xyz'
and A.OUNUM is NOT NULL
AND A.lastupd BETWEEN TO_CHAR('08-DEC-2008 00:00:00','DD-MON-YYYY HH:MI:SS')
AND TO_CHAR(SYSDATE,'DD-MON-YYYY HH:MI:SS')
A.lastupd - Is this a timestamp field or character?
If it is a timestamp then you converting your date in wrong type. It should be TO_TIMESTAMP and not TO_CHAR.
