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

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.



MORE INFORMATION
To create a Multiple Value Field crosstab query, you must create a separate crosstab query for each value that you want to calculate. You can then use a select query to join these crosstab queries to display the results that you want.

The following example uses the sample database Northwind.mdb to create a query that displays results similar to the example in the &quot;Summary&quot; section earlier in this article. It shows the number of sales and total for each year for each company.   Open the sample database Northwind.mdb, and then create the following crosstab query that is 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]) & &quot; &quot; & &quot;Order Total&quot; Table Name: Total: Group By     Crosstab: Column Heading

Field: Expr2: Sum(CCur([UnitPrice]*[Quantity]*(1-[Discount]))) Table Name: Total: Expression Crosstab: Value  Save this query as Order Total .  Create the following crosstab query that is 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]) & &quot; &quot; & &quot;Order Count&quot; Table Name: Total: Group By     Crosstab: Column Heading

Field: OrderID Table Name: Orders Total:     Count Crosstab:  Value  Save this query as Order Count .</li>  Create a query that is based on the Order Total and the Order Count crosstab queries. Use the CompanyName, 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. <pre class="fixed_text">  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 </li>  When you run the Multiple Values query, you will see a table that looks similar to the following table: <pre class="fixed_text">                        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 must add the table name to the expression if the field that is specified for the concatenation is a field in more than one of the tables that is joined in the query. For example, in step 1 you would change: <pre class="fixed_text">  Year([OrderDate]) & &quot; &quot; & &quot;Order Total&quot; to: <pre class="fixed_text">  Year([Orders].[OrderDate]) & &quot; &quot; & &quot;Order Total&quot; 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. </li></ol>
