Summary

By using crosstab queries, you can create summary views of your data for easier analysis. This article shows you how to create a crosstab query in Microsoft Access with and without using a wizard.

CAUTION: If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database.

Creating a Crosstab Query by Using the Crosstab Query Wizard

  1. Start Microsoft Access, and then open the sample database Northwind.mdb.
  2. On the View menu, point to Database Objects, and then click Queries.
  3. On the Insert menu, click Query.
  4. In the New Query dialog box, click Crosstab Query Wizard, and then click OK.
  5. On the first page of the Crosstab Query Wizard, click Orders from the list of tables, and then click Next.
  6. Double-click EmployeeID from the list of Available Fields to add it to the list of Selected Fields, and then click Next. This creates a query with one record per employee.
