MORE INFORMATION

The following example uses the IIf() function to list companies whose name begins with the letter "A" individually, and to group all other companies under the "OTHERS" column heading:

Open the sample database Northwind.mdb.

Create the following new crosstab query based on the Orders table and the Customers table:

      Query: MyQuery
      ---------------------------------------------------------
      Type: Crosstab query
      Join: Orders.[CustomerID]<->Customers.[CustomerID]

      Field: Country
         Table: Customers
         Total: Group By
         Crosstab: Row Heading
      Field: IIf([CompanyName] Like "A*",[CompanyName],"OTHERS")
         Total: Group By
         Crosstab: Column Heading
      Field: Order ID
         Table: Orders
         Total: Count
         Crosstab: Value

Run the query.
