SQL query not to SELECT something for a period of time

I've an sql query which SELECTs certain fields from a table if the (sysdate - upd_dt) * 1440 > 10
basically, this query is a perl script which gets executed every 5 mins
Now, I need to modify the query so that it doesn't selects anything if the system time is between 0000 and 0115

I dont want to decrease the frequency of the perl script as it does some other stuffs.

Is there any way to perform this?

You could try something like this :
SELECT * FROM MYTABLE
WHERE (sysdate - upd_dt) * 1440 > 10
AND TO_CHAR('HHMI', sysdate) < '0115'

BillAb1 and annamalai77 are on the good way, so give points to them.
But they should read more carefully, because the question is in the negative way, thus add a NOT to the condition:

SELECT *
FROM MYTABLE
WHERE (sysdate - upd_dt) * 1440 > 10
AND NOT TO_CHAR(sysdate, 'HHMI') between '0000' and '0115'

respectively:
ELECT * FROM MYTABLE
WHERE (sysdate - upd_dt) * 1440 > 10
AND TO_CHAR('HHMI', sysdate) > '0115'

hi the correct query

a minor correction as said by angel

SELECT *
FROM MYTABLE
WHERE (sysdate - upd_dt) * 1440 > 10
AND to_number(TO_CHAR(sysdate, 'HHMI')) not between 0000 and  0115

Hi annamalai77,
may you tell us why you use to_number?
0
annamalai77Commented:
hi angel

just to convert the character data to numeric data thats all. even without to_number the query will work but to avoid any problems which might arise i have used to_number.

Thanks for the suggestions ---
do I need to change the below
to_number(TO_CHAR(sysdate, 'HHMI'))

to
to_number(TO_CHAR(sysdate, 'HH24MI'))
in order to get the 24 hrs clock?
