that the size of a numeric value that is being imported into a table is *too large* or *too small* for the field type. For example, a field that is set http://answers.microsoft.com/en-us/msoffice/forum/msoffice_access-mso_other/access-2003-overflow-error/bb9e4c66-661c-4de3-990f-15112836c77a for Integer can handle values between -32,768 and 32,767. If you try to put the number 1,000,0000 into this field, the "overflow" message error will occur. -- Ken Snell

"Overflow" error P: n/a SheldonMopes I sometimes get a pop-up box that https://bytes.com/topic/access/answers/472271-overflow-error reads "Overflow" and the module that is executing pauses. It doesn't get caught by https://bytes.com/topic/access/answers/911133-access-sql-error-overflow my error trapping, and it seems to be randow. By random, I mean usually in the same section of code, but I can run the code a few times, then it appears. I can't reproduce it when I want to, and I have no idea what is causing it. Any ideas ? Thanks By the way the overflow error code is some record manipulation of 2 recordsets. Mar 24 '06 #1 Post Reply Share this Question 3 Replies P: n/a Allen Browne Overflow means that the data is too large for the data type that is trying to handle it. Open the Immediate Window (Ctrl+G), and enter: ? 200 * 200 The default number type in Access is Integer, and the largest integer is 32767. Therefore this simple calculation fails microsoft access overflow with an Overflow error. The solution is to force one of the numbers to be a Long integer, e.g.: ? CLng(200) * 200 Your calculations may therefore need typecasting to a Long, Double, or Currency, using CLng(), CDbl(), or CCur(). Note that these types do not handle Null, so you usually need to use Nz() inside those expressions too, e.g.: CCur(Nz([Quantity],0)) * [PriceEach] More info: Calculated fields misinterpreted at: http://allenbrowne.com/ser-45.html -- Allen Browne - Microsoft MVP.

Access SQL error "Overflow" P: 39 Amy Badgett I keep getting the error: "Overflow" with this piece of MS Access SQL coding: Expand|Select|Wrap|Line Numbers SELECTDISTINCT (SELECTCount(tblCallLog.tblCallLog_gospelPresented)FROMtblCallLogWHEREtblCallLog.tblCallLog_callDate=Date()ANDtblCallLog.tblCallLog_callDateIsNotNullANDtblCallLog.tblCallLog_gospelPresented=true)AStodaysGospelPres, (SELECTCount(tblCallLog.tblCallLog_gospelPresented)FROMtblCallLogINNERJOINtblClientsONtblCallLog.tblCallLog_clientID=tblClients.tblClients_clientIDWHEREtblCallLog.tblCallLog_callDate=Date()ANDtblCallLog.tblCallLog_callDateIsNotNullANDtblCallLog.tblCallLog_gospelPresented=trueANDtblClients.tblClients_jewish=true)AStodaysGospelPresJewish, (todaysGospelPres-todaysGospelPresJewish)AStodaysGospelPresGentile, Format((todaysGospelPresJewish/todaysGospelPres),"Percent")AStodaysJewishGospelPercent, (todaysGospelPresJewish&'('&todaysJewishGospelPercent&')')AScomboTodayJewishGospel FROMtblCallLogINNERJOINtblClientsONtblCallLog.tblCallLog_clientID=tblClients.tblClients_clientID; Does anyone have an idea why? Apr 2 '11 #1 Post Reply Share this Question 1 Reply Expert Mod 2.5K+ P: 2,543 Stewart Ross I think the most likely explanation is that there is a division by zero error happening, which gives rise to the overflow exception. Check the data in the underlying query carefully, and in particular look for the value of todaysGospelPres being 0 somewhere. This field is an alias for the Count done in line 3. If you check line 9 of the SQL statement above you will see that this count is used as the divisor in the expression Format((todaysGospelPresJewish / todaysGospelPres), "Percent") One way of avoiding such an error is to test the value, and if it is 0 substitute a suitable value instead. There is more than one way to do this, so here are two examples: Expand|Select|Wrap|Line Numbers IIF(todaysGospelPres<>0,Format((todaysGospelPresJewish/todaysGospelPres),"Percent"),null) Format((todaysGospelPresJewish/IIF(todaysGospelPres=0,1,todaysGospelPres)),"Percent") The first method has the advantage that a null value is substituted for the whole expression
