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

If you upsize a table that has a field with a data type of Text, theUpsizing Wizard will map the type to the Microsoft SQL Server 7.0 nVarChardata type instead of the VarChar data type. This happens even though theUpsizing Wizard report indicates that the column was mapped to VarChar.
Manually change the data types on SQL Server to the data type that you want.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was fixed in Access 2002.

Steps to Reproduce Problem

  1. Open the sample database Northwind.mdb.
  2. Make a copy of the Categories table and name it tblTest.
  3. Open tblTest in Design view and take a look at the data types of the fields. Note that CategoryName has a data type of Text.
  4. Close the tblTest table.
  5. On the Tools menu, point to Database Tools, and then click Upsizing Wizard.
  6. Upsize the database to either a new or an existing SQL Server database.
  7. In the Upsizing Wizard, select the tblTest table to be upsized.
  8. When the wizard is finished, you see in the Upsizing Wizard report that the type column of the CategoryName field is VarChar.
  9. On a computer with the full version of SQL Server 7.0 installed, in SQL Server Enterprise Manager, open the database that you upsized to.
  10. Open the tblTest table in Design view.

    Note that the type column shows that CategoryName has a data type of nVarChar, not VarChar.
