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

SYMPTOMS

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 ')'.

CAUSE

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

RESOLUTION

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

Steps to Reproduce the Problem

Start the Registry Editor (Regedit.exe).
Open the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Access\Wizards\Preferences\Upsizer\Quiet
Set the value of this key to No, and then close the Registry Editor.
Start Microsoft Access, and then create a new database, Db1.mdb.

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

In the Database window, click Queries, and then double-click Create a new query in design view.
Click Close, and then click SQL on the Query Design toolbar.

In the SQL Editor, enter the following query:

   PARAMETERS [123456789012345678901234567890start] DateTime,    [123456789012345678901234567890end] DateTime;
   SELECT item, date
   FROM Table1
   WHERE date Between [123456789012345678901234567890start] And    [123456789012345678901234567890end];

Save the query as qryLongParameters, and then close the SQL Editor.
On the Tools menu, point to Database Utilities, and then click Upsizing Wizard.
Upsize your database to SQL Server.
