Using Crosstab Queries
A crosstab query summarizes query results by displaying one field in a table down the left side of the datasheet and additional facts across the top of the datasheet. A crosstab query can, for example, summarize the dollars sold by a salesperson to each company. You can place the name of each company in the query output's left-most column, and you can display each salesperson across the top. The dollars sold appear in the appropriate cell of the query output.Crosstab queries are probably one of the most complex and difficult queries to create. For this reason, Microsoft offers a Crosstab Query Wizard. The following sections explain the methods for creating a crosstab query with and without the Crosstab Query Wizard.
Creating a Crosstab Query with the Crosstab Query Wizard
Follow these steps to design a crosstab query with the Crosstab Query Wizard: 1. Select Query Wizard from the Other group on the Create tab. 2. Select Crosstab Query Wizard and click OK. 3. Select the table or query that will act as a foundation for the query (see Figure 12-20). If you want to include fields from more than one table in the query, you'll need to base the crosstab query on another query that has the tables and fields you want. Click Next. 4. Select the fields whose values you want to use as the row headings for the query output. In Figure 12.21, the CompanyName field is selected as the row heading. Click Next. 5. Select the field whose values you want to use as the column headings for the query output. In Figure 12.22, the Employee field is selected as the column heading. Click Next. 6. The Crosstab Query Wizard asks you to specify what field stores the number you want to use to calculate the value for each column and row intersection. In Figure 12.23, the Total field is totaled for each company and employee. Click Next. 7. Specify a name for your query. When you're done, click Finish.Figure 12.24 shows a completed crosstab query in Design view; take a look at several important attributes. Notice the Crosstab row of the query grid. The CompanyName field is specified as the row heading and is used as Group By columns for the query. The Employee field is included as a column heading; it is also used as a Group By for the query.
The Total is specified as a value. The Total cell for the column indicates that this field will be summed (as opposed to being counted, averaged, and so on).
