I was using the following query to try to find the differences between the results of a queries of two databases. I am not able to use the AccountID as a compare point since they don't line up between the different databases. The selects in the ctes both return 200105 rows but the result of the join on the cte has 201779 rows. The data in this case should be able to match up. Am I on the right track with this? If so what am I missing, or should I look to a different approach.\[code\] with cteDev3 (AccountID, SecurityID, UniqueAccountID, BuyPrice, BuyDate, Shares)as (select Al.AccountID, al.SecurityID,ad.UniqueAccountId, BuyPrice, BuyDate, Shares from dev3TMAd.dbo.AccountLot al join dev3TMAd.dbo.AccountDetails ad on al.AccountID = ad.AccountId where ad.EnterpriseId = 'HuberFinancial'), cteTest2 (AccountID, SecurityID, UniqueAccountID, BuyPrice, BuyDate, Shares)as (select Al.AccountID, al.SecurityID,ad.UniqueAccountId, BuyPrice, BuyDate, Shares from test2TMAd.dbo.AccountLot al join test2TMAd.dbo.AccountDetails ad on al.AccountID = ad.AccountId where ad.EnterpriseId = 'HuberFinancial')select c3.UniqueAccountId as 'Dev3' , t2.UniqueAccountId as 'Test2'from cteTest2 t2join cteDev3 c3 on c3.UniqueAccountId = t2.UniqueAccountId and c3.SecurityID = t2.SecurityID and c3.BuyDate = t2.BuyDate and c3.Shares = t2.Shares and c3.BuyPrice = t2.BuyPrice\[/code\]This is what the result sets look like for the subqueries that are part of the ctes:\[code\]AccountID | SecurityID | UniqueAccountId | BuyPrice | BuyDate | Shares949662 | 17030 | 11284035 | 42.690021 | 2007-12-19 00:00:00 | 4.710000949662 | 17030 | 11284035 | 42.690629 | 2007-12-19 00:00:00 | 13.521000949662 | 17030 | 11284035 | 42.611940 | 2007-12-19 00:00:00 | 0.134000949662 | 17030 | 11284035 | 39.323467 | 2008-03-10 00:00:00 | 0.946000949662 | 17030 | 11284035 | 40.831884 | 2008-06-10 00:00:00 | 6.323000949662 | 17030 | 11284035 | 30.730860 | 2008-09-09 00:00:00 | 6.335000949662 | 17030 | 11284035 | 16.290063 | 2008-12-10 00:00:00 | 111.045000950091 | 25885 | 11937183 | 14.629975 | 2012-03-23 00:00:00 | 12.337000950091 | 25885 | 11937183 | 14.599671 | 2012-04-23 00:00:00 | 12.140000950091 | 4325 | 11937183 | 11.082955 | 2012-01-27 00:00:00 | 6768.953000950091 | 4325 | 11937183 | 11.119163 | 2012-01-31 00:00:00 | 1.242000\[/code\]
