Both work, but yes, improved.....now I just need to spend the time to figure it all out....:-)

BTW, it works perfect on my 20,000 + rows, took 7 seconds total.....

Is there any way to replace the null values with a space?

Heh... I just knew that would be the next question and I should have done that to begin with.

SELECT PIN = ISNULL(PIN,''),

CDate = ISNULL(CDate,''),

BTN = ISNULL(BTN,''),

Descr = ISNULL(Descr,''),

CallCount,

CallDuration,

Charge

FROM

(

SELECT PIN,

CDate = CASE WHEN GROUPING(PIN) = 0 THEN 'SubTotal' ELSE 'Total' END,

BTN = NULL,

Descr = NULL,

CallCount = SUM(CallCount),

CallDuration = SUM(CallDuration),

Charge = SUM(Charge)

FROM #GMReport

GROUP BY PIN WITH ROLLUP

UNION ALL

SELECT PIN, CDate, BTN, Descr, CallCount, CallDuration, Charge

FROM #GMReport

)d

ORDER BY ISNULL(PIN,'Z'), CDate, BTN

;

Just curious... that included the time to output to the screen? If so, grid mode or text mode?

The reason I ask is because that just seems awfully slow to me.

Output to grid, and I am using a view that includes around 48 individual tables...

Ah... the VIEW might explain it. It's actually being executed twice if you're using it directly in the code I wrote. You'll get much better performance if you do a SELECT/INTO a temp table and point my code at the temp table because the view will only need to execute once that way. Thanks.

Yes, thats what I did, the select into the temp table is what takes the time, running the query on the temp table is milli seconds......thanks again, still awaiting the users input, but I think its exactly what the doctor ordered.

You bet. Thank you for the thoughtful feedback. Really appreciate it.
