Eclipse BIRT Report Developer Guide

In this procedure, you build a data set to indicate what data to extract from the Orders table. The orders subreport that you create later uses this data set.

On Query, in Available Items, expand CLASSICMODELS, then expand the Orders table to display the columns in the table.
This statement selects the ORDERNUMBER and ORDERDATE columns from the Orders table. The WHERE clause has a parameter marker for the value of CUSTOMERNUMBER. When the report runs, the orders subreport gets the current CUSTOMERNUMBER value from the customers report.
Choose Finish to save the data set. Edit Data Set displays the columns specified in the query, and provides options for editing the data set.
103 is one of the values in the CUSTOMERNUMBER column. A default value is required for BIRT Report Designer to run the query for testing purposes.

Choose OK to confirm your edits to the parameter definition. The parameter definition appears in Edit Data Set, as shown in Figure 13‑5.

Choose Preview Results to confirm that the query is valid and that it returns the correct data. If you created the SELECT statement and created the data set parameter correctly, you should see the results that appear in Figure 13‑6. These are the data rows that the data set returns for customer number 103.
