Linked Table Query Returning Incorrect Results

a7n9 — Wed, 18 Aug 2010 19:24:47 +0000

We had this annoying problem: a simple query in Access to a linked table (using ODBC and MS SQL server) returned incorrect results, though the same query returned correct results in MS SQL server. By incorrect I mean the field values were different, so rather than returning AZ, the query returned BZ (some other value in that field).

We thought that it was a table size issue, may be the driver could not handle huge data. However, the problem was with the “unique record identifier” while linking the table, as JM reported here. I did not have this problem any longer when I did not select any fields for the unique record identifier while linking the table.

Access to the VB project is not trusted

I was trying to enable an add-in for Excel 2007, and I kept getting this error:

Access to the VB project is not trusted

You can turn this message off by going to Developer tab in the ribbon and then clicking on the Macro security button, and checking the check box for “Trust access to the VBA project object model.”

A word of caution: be wary of the add-ins/projects that need VBA access. Don’t allow any project/add-in with VBA access, unless you know its exact purpose or the author of that project.

Access Export to Excel (2007)

When I tried to export a table/query from Access 2007 to Excel 2007, I was getting this annoying error:

You selected more records than can be copied onto the Clipboard at one time. Divide the records into two or more groups, and then copy and paste one group at a time. The maximum number of records you can paste at one time is approximately 65,000.

Access 2007 Export to Excel Error

I was unable to understand the reason, because I thought Excel 2007 did not limit number of rows to 65,536. It turns out however that it is the clipboard limitation.

Solution: If you check off the “export data with formatting and layout” option, Access exports successfully.

You can export successfully using Transferspreadsheet (VBA) option too.

Here is the KB from MS.

Solution Update:Thanks to Brett, it looks like that only if you export table/query using right click > Export and have the checkbox cleared, then Access will export succesfully. That is what I always do, and it works for me. I have never tried External data option for exporting.
