ACC95: Error Exporting MS Access 95 Table to Version 2.0

ID: Q145771

The information in this article applies to:

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

If you try to export a Microsoft Access version 7.0 table to a Microsoft Access version 2.0 database, you may receive the following error message:

Invalid field data type.


CAUSE

The Microsoft Access 7.0 table contains a field with a ReplicaID field size. The ReplicaID field size is a Globally Unique Identifier (GUID), 16 bytes long. Microsoft Access version 2.0 does not support the ReplicaID field size. Although Microsoft Access version 7.0 will convert a field with a ReplicaID field size to the Text data type when it exports the table to a file format like text-delimited or dBASE, it will not convert the field's data type if the export is to a version 2.0 database.


RESOLUTION

If you want to export a version 7.0 table that contains a field with a ReplicaID field size to a version 2.0 database, do one of the following:

Create a select query containing all fields except the field with a Replica ID field size, and then export the query.

-or-

Export the table to another file format, such as text-delimited or dBASE, and then import the file into the version 2.0 database.


STATUS

This behavior is by design.


MORE INFORMATION

Steps to Reproduce Behavior


  1. Start Microsoft Access 7.0.


  2. Create the following new table and called it Table1: 
    
      Table: Table1
      -----------------------------------
      Field Name: ID
         Data Type : AutoNumber or Number
         Field Size: Replication ID
      Field Name: FName
         Data Type : Text


  3. Save and close the Table1 table without defining a primary key.


  4. On the File menu, click Save As/Export.


  5. In the Save As dialog box, click "To an external File or Database," and then click OK.


  6. In the Save Table 'Table1' dialog box, click Save Microsoft Access (*.mdb, *.mdw, *.mda) in the Save As Type box, locate a version 2.0 database, and then click Export.


  7. In the Export dialog box, click OK. Note that you receive the following error message:
    Invalid field data type.


NOTE: Step 2 in the example is just one method of creating a field with a ReplicaID field size. If a table is in a replicated database and the table is replicable, it automatically contains a field named s_Guid. This field has a ReplicaID field size, and cannot be deleted.
