Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

This article applies only to a Microsoft Access database (.mdb).

When you attempt to upsize your database, you may receive an error message similar to the following:
Server Error 134: The variable name '@Forms......' has already been declared. Variable names must be unique within a query batch or stored procedure.

Server Error 170: Line 7: Incorrect syntax near ')'.
This behavior can occur if queries in your database contain parameters that match through the first 30 characters. For example, the following query produces the error message:
   PARAMETERS [123456789012345678901234567890start] DateTime,    [123456789012345678901234567890end] DateTime;   SELECT item, date   FROM Table1   WHERE date Between [123456789012345678901234567890start] And    [123456789012345678901234567890end];				
Note that this query contains two parameters that match each other through the first 30 characters:
  • [123456789012345678901234567890start] DateTime
  • [123456789012345678901234567890end] DateTime
To resolve this issue, change the parameter names in such a way that they differ within the first 30 characters. For example, if your query contains the following two parameters
  • [123456789012345678901234567890start] DateTime
  • [123456789012345678901234567890end] DateTime
you can change the parameters to the following:
  • [start123456789012345678901234567890] DateTime
  • [end123456789012345678901234567890] DateTime
Note that the Upsizing Wizard accepts only the first 30 characters, so the resulting SQL query contains the following parameters:
  • (@start1234567890123456789012345) DateTime
  • (@end123456789012345678901234567) DateTime
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  1. Start the Registry Editor (Regedit.exe).
  2. Open the following registry key:
  3. Set the value of this key to No, and then close the Registry Editor.
  4. Start Microsoft Access, and then create a new database, Db1.mdb.
  5. Create a new table in Db1.mdb:
       Table: Table1   ----------------------   Field Name: ID   Data Type:  Text   PrimaryKey: Yes   Field Name: Date   Data Type:  Date/Time   Field Name: Item   Data Type:  Text					
  6. In the Database window, click Queries, and then double-click Create a new query in design view.
  7. Click Close, and then click SQL on the Query Design toolbar.
  8. In the SQL Editor, enter the following query:
       PARAMETERS [123456789012345678901234567890start] DateTime,    [123456789012345678901234567890end] DateTime;   SELECT item, date   FROM Table1   WHERE date Between [123456789012345678901234567890start] And    [123456789012345678901234567890end];					
  9. Save the query as qryLongParameters, and then close the SQL Editor.
  10. On the Tools menu, point to Database Utilities, and then click Upsizing Wizard.
