Subject Strange Query Results
Author sgharp
Hi All,

I'm using FB v1.5 and IBExpert v2004.08.05. I've found a situation
where the query result set seems really wierd.

select sum(iu.QtySold * iu.ItemPrice), sum(iu.QtyUsed * iu.ItemPrice)
from xItemUsages iu
where iu.MinorID = 900033

yields results of $2,538.6535 and $2,718.5150.

However,

select sum(iu.QtySold * iu.ItemPrice), sum(iu.QtyUsed * iu.ItemPrice)
from xItemUsages iu
join xLedgItem li on li.InvItemID = iu.InvItemID
where iu.MinorID = 900033

yields results of $19,769.4608 and $21,230.3890.

My original intent was to add the sum of a field in the xLedgItem
table but, when I added the join to that table, my result set when
crazy. As you can see, I have no ambiguous field references and all
the fields in both result sets are exactly the same. The only
difference is the join line.

Where is this result coming from?

Thanks for any help in understanding this,
Steve
