XL: "Unable to Write to Database" Error with Null String

 Last reviewed: January 9, 1998
Article ID: Q174972
The information in this article applies to:
  • Microsoft Excel 97 for Windows
  • Microsoft Excel for Windows 95, version 7.0

SYMPTOMS

If you are saving a template that was created by using the Template Wizard in Microsoft Excel, you may receive the following error message 

   Unable to write data to database. Make sure database is not protected
   and has valid field data-types.
and you cannot save data to the database.

CAUSE

This problem occurs when all of the following conditions are true:

  • You are saving your data to a Microsoft Access database. 

        -and-
  • One of the fields in your Access database is linked to a worksheet cell that contains a formula. 

        -and-
  • The formula returns a null string ("").

WORKAROUND

To work around this problem, modify the worksheet formula so that it does not return a null string ("").

For example, if the worksheet contains the following formula 

   A1: 1   B1: =IF(A1=1,"","not 1")
and cell B1 is linked to a field in your database, you receive the error message when you try to save data. To prevent the message from appearing, change the formula in cell B1 to the following: 

   =IF(A1=1," ","not 1")
NOTE: The only difference between the two formulas is that the second one contains a space between the quotation marks.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The Template Wizard with Data Tracking add-in creates a template that links selected cells in a workbook to fields in a database. When you base a new workbook on the template and enter data in the linked cells, Microsoft Excel creates a new record in the database and copies the data to the corresponding data fields.
