When you try to export a query in dBASE (any version) file format, you receive the following error message:

Couldn't find object queryname.dbf.
When you try to save the underlying table to dBASE format, you receive the following error message:

Cannot define field more than once.
When you try to export the query using the TransferDatabase method, you receive the following error message:

Run-time error '3191':
Can't define field more than once.


dBASE has a 10-character limit for the size of field names. When the first 10 characters of two (or more) fields in a Microsoft Access table are identical, trying to export the table or query results in duplicate field names.


To work around this behavior, use one of the following approaches:

  1. Rename the table fields so that the first 10 characters are unique for each field.
  2. Alias the field names in a query. For example, in the query field row type: [NewField]:[OldDuplicateField]

Steps to Reproduce Behavior

  1. Create the following table:

    Table: Table1
    Field Name: abcdefghijk
    Data Type : Text
    Field Name: abcdefghijkl
    Data Type : Text
  2. Create a query based on Table1 that includes both fields.
  3. On the File menu, click Save As/Export.
  4. In the Save As dialog box, click "To an External File or Database," and then click OK.
  5. Under Save As Type, select dBASE III (*.dbf), and then click Export. The error message "Couldn't find object Table1.dbf" appears.
