Query Overflow Error Access
Contents |
I continuously get an overflow message in access when i am trying to download a report in my database. Does this mean that the database has too much information in it? What can be down to fix this problem? Guest, Sep access 2013 overflow error 30, 2004 #1 Advertisements Ken Snell [MVP] Guest Most likely it means that the size of access 2007 overflow error a numeric value that is being imported into a table is *too large* or *too small* for the field type. For example, a field overflow when running access query that is set 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

few rows of each column, and tries to determine whether it is Text, Date, Number, etc. If later columns prove to have wildly different values, its original decision about the type and size required may prove inadequate - particularly for Number fields. There are several workarounds, depending on where the data is coming from. If you are importing a Text file, you can click the Advanced button once you are in the Import Wizard, and you can define the data types of the fields you want to use. You can then save this Import Specification, and tell Access to use it again next time you perform a TransferText. If you are importing from Excel, see: "Numeric Field Overflow" error message occurs when you query a table that is linked to Excel spreadsheet at: http://support.microsoft.com/default.aspx?scid=kb;en-us;815277&Product=acc or Import, export, and link data between Access and Excel at: http://office.microsoft.com/en-au/assistance/HP010950951033.aspx?Product=acc The overflow is very easy to demonstrate: 1. Open the Immediate window by pressing Ctrl+G. 2. Enter: ? 200 * 200 You receive an overflow, because Access treats these numbers as type Integer. When you multiply them, the result is bigger than 32767 (the largest integer), and so the integer type overflows. You can avoid this problem by forcing Access to treat at least one of the numbers as a Long Integer: ? CLng(200) * 200 -- Allen Browne - Microsoft MVP. Perth, Western Australia.

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
