SUMMARY

Novice: Requires knowledge of the user interface on single-user computers.

In a Microsoft Access crosstab query, you can specify only one field or calculation as the value. Often, you may want to show more than one value in the query.

For example, the following example shows two columns of information per company, a count of the number of orders, and the order totals for each year:
   Company Name  1998 Orders  1998 Total  1999 Orders  1999 Total
   --------------------------------------------------------------
   ABC Company   12           $855.00     15           $1010.25
   XYZ Company   1017         $22045.57   1050         $25345.29
				
This type of query is sometimes called a Multiple Value Field query.

NOTE: You can see a demonstration of the technique that is used in this article in the sample file Qrysmp00.exe. For information about how to obtain this sample file, please see the following article in the Microsoft Knowledge Base:

MORE INFORMATION

In order to create a Multiple Value Field crosstab query, you must create a separate crosstab query for each value that you want to calculate. These queries can then be joined, using a select query to display the desired results.

The following example uses the sample database Northwind.mdb to create a query that displays results similar to the example in the "Summary" section earlier in this article. It shows the number of sales and total for each year for each company.
  1. Open the sample database Northwind.mdb and create the following crosstab query based on the Orders, Order Details, and the Customers tables:
       Query: Order Total
       ------------------
       Type: Crosstab Query
       Join: Customers.[CustomerID] <-> Orders.[CustomerID]
       Join: Orders.[OrderID] <-> Order Details.[OrderID]
    
       Field: CompanyName
          Table Name: Customers
          Total: Group By
          Crosstab: Row Heading
    
       Field: Expr1: Year([OrderDate]) & " " & "Order Total"
          Table Name:
          Total: Group By
          Crosstab: Column Heading
    
      Field: Expr2: Sum(CCur([UnitPrice]*[Quantity]*(1-[Discount])))
          Table Name:
          Total: Expression
          Crosstab: Value
    					
  2. Create the following crosstab query based on the Orders and the Customers tables:
       Query: Order Count
       ------------------
       Type: Crosstab Query
       Join: Customers.[CustomerID] <-> Orders.[CustomerID]
    
       Field: CompanyName
          Table Name: Customers
          Total:      Group By
          Crosstab:   Row Heading
    
       Field: Expr1: Year([OrderDate]) & " " & "Order Count"
          Table Name:
          Total: Group By
          Crosstab: Column Heading
    
       Field: OrderID
          Table Name: Orders
          Total:      Count
          Crosstab:   Value
    					
  3. Create a query based on the Order Total and Order Count crosstab queries. You will use CompanyName as well as the Order Total and Order Count fields for the years whose results you want to view. The following example uses the last two years of Order Total and Order Count in Microsoft Access.
       Query: Multiple Values
       ----------------------
       Join: Order Total.[CompanyName] <-> Order Count.[CompanyName]
    
       Field: CompanyName
          Table Name: Order Count
    
       Field: 1997 Order Count
          Table Name: Order Count
    
       Field: 1997 Order Total
          Table Name: Order Total
    
       Field: 1998 Order Count
          Table Name: Order Count
    
       Field: 1998 Order Total
          Table Name: Order Total
    					
Running the Multiple Values query results in a table that looks like the following:
                         1997 Order  1997 Order  1998 Order  1998 Order
   Company Name            Count       Total       Count       Total
   --------------------------------------------------------------------
   Alfred's Futterkiste        3      $2,022.50        3      $2,022.50
   Ana Trujillo                2        $799.75        1        $514.10
   Antonio Moreno              5      $5,960.78        1        $660.00
				
NOTE: You need to add the table name to the expression if the field specified for the concatenation is a field in more than one of the tables joined in the query. For example, in Step 1 you would change:
   Year([OrderDate]) & " " & "Order Total"
				
to:
   Year([Orders].[OrderDate]) & " " & "Order Total"
				
If you add the table name to the Table row, you generate a syntax error. If you leave the table name out completely, you generate an ambiguous reference error.
