SQL Statement help

Posted on 2004-08-10

Please review this previous question for further info:

That worked great.  The problem now is some of my results are a little off.  The AvgAmt, MaxAmt, and MinAmt are off.  They should not include in the records in the average that the "Num" field is 0.  Currently they do.  

I tried adding this to the statement for the AvgAmt field but it is not right even though it executes fine:

Avg(Case WHEN Bids > 0 THEN Amt Else 0 End) as 'TestAmt'

I get $17.59 when it should be $138.37

PLEASE HELP!!!  Thanks in advance.

Why not to use where clause?
Avg(Amt) as 'TestAmt' where Bids<>0

Replace your zero with a null.  Average doesn't count null values.

So you should have this...

Avg(Case WHEN Bids > 0 THEN Amt Else null End) as 'TestAmt'

Same thing applies to the Min and Max functions.
