25.2 Create a Single-Query Matrix

You can build a matrix report with a single query in the data model. A single-query data model typically performs better than a multiple-query data model.

When you are creating a single-query report, such as this one, you can use the Report Wizard to create the data model and layout simultaneously.

To create a data model and layout:

  1. Launch Reports Builder (or, if already open, choose File > New > Report).

  2. In the Welcome or New Report dialog box, select Use the Report Wizard, then click OK.

  3. If the Welcome page displays, click Next.

  4. On the Report Type page, select Create Paper Layout Only, then click Next.

  5. On the Style page, type a Title for your report, select Matrix, then click Next.

  6. On the Data Source page, click SQL Query, then click Next.

  7. On the Data page, enter the following SELECT statement in the Data Source definition field:



    You can enter this query in any of the following ways:

    • Copy and paste the code from the provided text file called matrix1qb_code.txt into the Data Source definition field.

    • Click Query Builder to build the query without entering any code manually.

    • Type the code in the Data Source definition field.

  8. Click Next.


    If you are not already connected to a database, you will be prompted to connect to the database when you click Query Builder or Next. Ensure that you connect to a database that has the appropriate schema for this example. Section 25.1, "Prerequisites for This Example" describes the sample schema requirements for this example.

  9. On the Rows page, click DEPTNO and click the right arrow (>) to move this field to the Matrix Row Fields list, then click Next.

  10. On the Columns page, click JOB and click the right arrow (>) to move this field to the Matrix Column Fields list, then click Next.

  11. On the Cell page, click SUM_SAL and click the right arrow (>) to move this field to the Matrix Cell Fields list, then click Next.


    In this case, the query itself performs the summary through the SUM function. Hence, you should not use the Sum button in this instance.

  12. On the Totals page, click Next.

  13. On the Labels page, delete the labels for all of the fields, then click Next.

  14. On the Template page, make sure Beige is selected under Predefined Template, then click Finish to display your report output in the Paper Design view. It should look like this:
