Have you checked the actual value that causes the error?

Have you checked the actual value that causes the error?Click to expand... I couldn't tell if it was just one value or not. 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!

Error message "Overflow" - what does https://bytes.com/topic/access/answers/208195-error-message-overflow-what-does-mean it mean P: n/a Andy Davis Dear Group I am trying to automate process of adding a new record id in my form using the following code when the user clicks the "Add New Record" button. http://stackoverflow.com/questions/26405840/overflow-error-of-sql-query-on-ms-access For example if the last record id is "2005001" then I want to increment this by one so that new value is "2005002" and place it in the record id field for the new record on overflow error the form. I've tried using the following code but get the message "Overflow" when I run the code. Can't find on the online help what this means. Not sure if the logic is correct in the code? Any pointers or ideas would be much appreciated. Code: On Error GoTo Err_Command623_Click Dim intlastrecID As Integer DoCmd.GoToRecord , , acLast intlastrecID = PropID.Value DoCmd.GoToRecord , , acNewRec PropID.Value = intlastrecID + 1 Exit_Command623_Click: overflow error in Exit Sub Err_Command623_Click: MsgBox Err.Description Resume Exit_Command623_Click Many thanks in advance Nov 13 '05 #1 Post Reply Share this Question 2 Replies P: n/a Allen Browne Overflow means the number is too great for the type of variable. Integers go up to 32767 only. Replace the declaration line with a long, e.g.: Dim lngLastRecId As Long If the form was filtered or sorted differently, the last record could contain a value that is not the highest. Also, if there are no records, the assignment of a Null to an Integer or Long will fail. Safer to lookup the highest number yet assigned directly in the table, and this avoids jumping around the records as well: lngLastRecId = Nz(DMax("PropId", "Table1"), 0) -- Allen Browne - Microsoft MVP.

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 = t2.id) INNER JOIN table3 AS t3 ON t1.id = t3.id WHERE t1.ID <> "" ) ) * It is possible to specify a join condition that will always eva
