Have you checked the actual value that causes the error?

If I copy the sql to design view I just get the overflow error immediately. I then removed the calcs and the query would run. Then I started playing around to see if I could get the calculations to work. I changed all values in the original table to doubles and set the "group by" total to expression. I have it working for now, so I hope that will suffice. Thanks! Roger rconverse, Jan 8, 2008 #4 This thread has been Locked and is not open to further replies.

For example, add to qryClaimComparisonYTD the column ([Free]+[Reduced])/[FRNtotal] AS FRPercentage and then set the criteria in your current query to WHERE FRPercentage < 0.35 OM Gang 0 LVL 47 Overall: Level 47 MS Access 46 Message Active today Expert Comment by:Dale Fye (Access MVP)2014-09-24 Your problem is obviously where FRNTotal is either NULL, zero, or extemely small. You might want to consider something like: SELECT qryClaimComparisonYTD.[Center Name] , qryClaimComparisonYTD.ClaimDate , qryClaimComparisonYTD.Free , qryClaimComparisonYTD.Reduced , qryClaimComparisonYTD.[Non-Needy] , qryClaimComparisonYTD.FRNTotal , IIF(NZ([FRNTOTAL], 0) < .0001, 100, ([Free]+[Reduced])/[FRNtotal]) AS FRPercentage FROM qryClaimComparisonYTD WHERE (((([Free]+[Reduced])/[FRNtotal])<0.35)); This would give you a percentage of 100 for those where [FRNTotal] is NULL or zero. 0 LVL 48 Overall: Level 48 MS Access 47 Message Active today Expert Comment by:Gustav Brock2014-09-24 First, do not attach simple code as a document. Then protect against Null values of FRNtotal: SELECT qryClaimComparisonYTD.[Center Name], qryClaimComparisonYTD.ClaimDate, qryClaimComparisonYTD.Free, qryClaimComparisonYTD.Reduced, qryClaimComparisonYTD.[Non-Needy], qryClaimComparisonYTD.FRNT

SELECT max( v_difference ) AS max_v_difference FROM ( SELECT *, vv1 - vv2 AS v_difference , FROM ( SELECT table3.* , table1.v1 AS vv1, table2.v1 AS vv2 FROM table1, table2, table3 where table1.id = table2.id and table1.id <> "" and table3.id = table1.id ) ) I got error: "overflow" Any help would be appreciated. thanks sql ms-access windows-7 ms-access-2010 share|improve this question asked Oct 16 '14 at 13:34 user3601704 358311 Why no JOIN between table1, table2, and table3? –PaulFrancis Oct 16 '14 at 13:43 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote I'm guessing it has to do with the fact that you are performing implicit cross joins with your innermost subquery. While some SQL engines will optimize those types of queries automatically, MS Access is not one of them. A cross join returns the Cartesian product of two tables; the Cartesian product is a combination of every row from one table combined with every row from another table. So if table1 has 1,000 rows and table2 has 1,000 rows then the Cartesian product of those tables has 1,000 x 1,000 = 1,000,000 rows. The situation gets worse quickly as you add tables. If your table3 has 10,000 rows, then the Cartesian product of all three tables is 1,000 x 1,000 x 10,0000 = 10,000,000,000 rows. You can see how combining even modestly sized tables could quickly overwhelm system resources and result in an overflow error. When you do an INNER JOIN, the resulting rowset is the intersection of the tables where the specified JOIN condition is met. This (almost*) always results in a smaller result set than a CROSS JOIN. You should use INNER JOINs instead. Try the following: SELECT max( v_difference ) AS max_v_difference FROM ( SELECT vv1 - vv2 AS v_difference FROM ( SELECT t1.v1 AS vv1, t2.v1 AS vv2 FROM (table1 AS t1 INNER JOIN table2 AS t2 ON t1.id =
