Can't do a whole lot for you if you don't post the "simple structure" of the data you're talking about... please click on, read, and provide the information from the...

In the meantime, please try to figure out what dateformat you'd like for startdate and enddate... I recommend not using one at all.

Jeff,

Thanks a lot for your help!

I have purified one more time.

DECLARE @DateStart DATETIME

DECLARE @DateEnd DATETIME

SELECT @DateStart = '07/Apr/2008', @DateEnd = '29/Dec/2008'

SELECT Month = convert(varchar,DatePart(MM,DATEADD(mm,N-1,@DateStart))),

...

If the data is all in one table, there's no need to make it in two separate tables... you can make it appear as if you did that with table...

You both really need to make a trip to Books Online... and, just to be sure, you can do INSERTs, UPDATEs, and DELETEs on Table Variables in a UDF... just...

In this case, I'd say no indexes are necessary on the source table and for speed, the fewer indexes on the target table, the better. If the target table...

This will do it...

--===== Create a table to demo with

DECLARE @DemoTable TABLE (IPAddr VARCHAR(15))

INSERT INTO @DemoTable (IPAddr)

SELECT '192.168.215.1' UNION ALL

SELECT '192.168.23.1' UNION ALL

SELECT '192.168.5.1' UNION ALL

...

Heh... skip the "trees"... try this...

SELECT ABS(YEAR(DATEADD(dd,DATEDIFF(dd,@BirthDate,@ReferenceDate),0)-1)-1900)

So, which columns constitute a dupe? Just the first two or all of them?

I believe every one has hit all the hot spots... Carl's last post should be a big help, as well. The problem is that the derived table in the...

That covers just about all of it... can't think of anything else to check unless the WHERE clauses have a formula in one and not the other.

Grant is correct. Tell us what needs to be done... not how to do it. There's usually no need for any form of RBAR. Post some data...

Jeff,

I have refined the above code as

DECLARE @DateStart DATETIME

DECLARE @DateEnd DATETIME

SELECT @DateStart = '04/Apr/2007', @DateEnd = '29/Apr/2008'

SELECT convert(Datetime,'01'+'/'+convert(varchar,DatePart(MM,DATEADD(mm,N-1,@DateStart)))+'/'+convert(varchar,DatePart(YY,DATEADD(mm,N-1,@DateStart))),103),

DateAdd(DD,-1,convert(Datetime,'01'+'/'+convert(varchar,DatePart(MM,DATEADD(mm,N,@DateStart)))+'/'+convert(varchar,DatePart(YY,DATEADD(mm,N,@DateStart))),103))

FROM dbo.Tally

where DateAdd(DD,-1,convert(Datetime,'01'+'/'+convert(varchar,DatePart(MM,DATEADD(mm,N,@DateStart)))+'/'+convert(varchar,DatePart(YY,DATEADD(mm,N,@DateStart))),103)) <= @DateEnd

I got the below output:
