Re: Problem with date query - simple?

I had the current time check, but how do I incorporate that into the where clause?

I have (from a programmatic stand-point - more or less):

if (TO_CHAR(sysdate,'hh24:mi:ss') > ('20:00:00')) then

	RDATE between ('round(sysdate) 18:00:00','DD-MM-YY hh24:mi:ss")
		and  ('round(sysdate) 22:00:00','DD-MM-YY hh24:mi:ss")
else
	RDATE between ('round(sysdate-1) 18:00:00','DD-MM-YY hh24:mi:ss")
		and  ('round(sysdate-1) 22:00:00','DD-MM-YY hh24:mi:ss")

Obviously the above wouldn't work, but it's basically what I want to do, but can't figure out how to get the above concept into the where clause.

My mind just can't wrap around this for some reason.

Any more help would be appreciated.

Thanks,

Don
