Datetime Comparison Problem
Hi,
I have a comparison problem. I have table that you can see below. It's like this:
RECTIME1 RECTARIH1
10:00:00 22.10.2007
06:00:00 10.10.2007
03:00:00 13.05.2007

There is no date data in RECTIME1 and there is no time data in RECTARIH1.

I want to query the RECTIME1 column which includes time data. I try
Code:
WHERE RECTIME1 < '10:00:00' AND RECTIME1 > '06:00:00'
but the query returns nothing. I didnot make the table, somebody did. I am sure that RECTIME1 is datetime (8-bit). What should I do?
Thanks

Switch to just one column holding date with time, will make your life much easier (not only for this specific query)

Thanks for your response. I will switch one column later. But, we have lots of records in this table. I have to make this query. So I need help.

Mayhap using the datepart functionality would be good enough for you

WHERE
Datepart(hh,RECTIME1) < 10 AND
Datepart(hh,RECTIME1) >= 6

Thank you so much.

Read up on SQL book online (BoL). The number of Date/time functions available is quite daunting at first, but each is very very useful in the correct circumstances.
