SUMMARY
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  1989 Orders  1989 Total  1990 Orders  1990 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: A demonstration of the technique used in this article can be seen in the sample file, Qrysmp97.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 Fields crosstab query, you must create two separate crosstab queries with fixed column headings for each value you want to calculate. These two queries can then be joined, using a Select query to display the desired results.

The following example uses the sample database Northwind.mdb in Microsoft Access version 7.0 and Microsoft Access 97 (or NWIND.MDB in versions 2.0 or earlier) to create a query that displays results similar to the example above, showing the number of sales and total for each year for each company.

Step One: Create the Order Total Crosstab Query
To create the Order Total Crosstab query, follow these steps:   Open the sample database Northwind.mdb (or NWIND.MDB in version 2.0 or earlier) 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]

NOTE: In versions 1.x and 2.0, there is a space in Customer ID.

Join: Orders.[OrderID] <-> Order Details.[OrderID]

NOTE: In versions 1.x and 2.0, there is a space in Order ID.

Field: CompanyName Table Name: Customers Total: Group By        Crosstab: Row Heading

NOTE: In versions 1.x and 2.0, there is a space in Company Name.

Field: Expr1: Year([OrderDate]) & " " & "Order Total" Table Name: Total: Group By        Crosstab: Column Heading

NOTE: In versions 1.x and 2.0, there is a space in Order Date.

Field: Expr2: Sum(CCur([UnitPrice]*[Quantity]*(1.-[Discount]))) Table Name: Total: Expression Crosstab: Value

NOTE: In versions 1.x and 2.0, there is a space in Unit Price.   Select the query by clicking anywhere on the gray area in the top half of the query grid. Click Query Properties on the View menu, select the Fixed Column Headings check box, and in the Fixed Column Headings box type the entries appropriate for your version of Microsoft Access:      Version 1.x:      "1989 Order Total";"1990 Order Total";"1991 Order                        Total";"1992 Order Total"

Version 2.0:     "1991 Order Total";"1992 Order Total";"1993 Order                        Total";"1994 Order Total"

Version 7.0:     "1993 Order Total";"1994 Order Total";"1995 Order                        Total"

Version 97:      "1994 Order Total";"1995 Order Total";"1996 Order                        Total" 

NOTE: In Microsoft Access versions 2.0, 7.0, and 97, the FixedColumnHeadings property is called Column Headings.

Step Two: Create the Order Count Crosstab Query
  Create the following Crosstab query based on the Orders and the Customers tables:      Query: Order Count --     Type: Crosstab Query Join: Customers.[CustomerID] <-> Orders.[CustomerID]

NOTE: In versions 1.x and 2.0, there is a space in Customer ID.

Field: CompanyName Table Name: Customers Total:     Group By         Crosstab:   Row Heading

NOTE: In versions 1.x and 2.0, there is a space in Company Name.

Field: Expr1: Year([OrderDate]) & " " & "Order Count" Table Name: Total: Group By        Crosstab: Column Heading

NOTE: In versions 1.x and 2.0, there is a space in Order Date.

Field: OrderID Table Name: Orders Total:     Count Crosstab:  Value

NOTE: In versions 1.x and 2.0, there is a space in Order ID. </li>  Select the query by clicking anywhere on the gray area in the top half of the query grid. Click Query Properties on the View menu, select the Fixed Column Headings check box, and in the Fixed Column Headings box type the entries appropriate for your version of Microsoft Access: <pre class="fixed_text">     Version 1.x:      "1989 Order Count";"1990 Order Count";"1991 Order                        Count";"1992 Order Count"

Version 2.0:     "1991 Order Count";"1992 Order Count";"1993 Order                        Count";"1994 Order Count"

Version 7.0:     "1993 Order Count";"1994 Order Count";"1995 Order                        Count"

Version 97:      "1994 Order Count";"1995 Order Count";"1996 Order                        Count" </li></ol>

NOTE: In Microsoft Access versions 2.0, 7.0, 97, the FixedColumnHeadings property is called Column Headings.

Step Three: Create the Multiple Values Query
  Create a Select 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 example below uses the last two years of Order Total and Order Count in Microsoft Access 97. <pre class="fixed_text">     Query: Multiple Values --     Join: Order Total.[CompanyName] <-> Order Count.[CompanyName]

NOTE: In versions 1.x and 2.0, there is a space in Company Name.

Field: CompanyName Table Name: Order Count Show: Yes Field: 1995 Order Count Table Name: Order Count Show: Yes Field: 1995 Order Total Table Name: Order Total Show: Yes Field: 1996 Order Count Table Name: Order Count Show: Yes Field: 1996 Order Total Table Name: Order Total Show: Yes </li></ol>

Running the Multiple Values query results in a table that looks like the following: <pre class="fixed_text"> Company Name         1995 Order Count 1995 Order Total 1996 Order Count.. -- Alfred's Futterkiste 3                $2,022.50        3 Ana Trujillo         2                  $799.75        1 Antonio Moreno       5                $5,960.78        1

NOTE: This technique does not work if the field specified for the concatenation (Step One(expr1)) is a field in more than one of the tables joined in the query. There is no way to force the query to accept the table name in the expression without generating reserved error -1310. 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.
