How to use a stored procedure to retrieve data from a JDBC data source

This procedure assumes you have already created the JDBC data source that this data set uses.

1	In Data Explorer, right-click Data Sets, then choose New Data Set.

2	On New Data Set, specify the following information:

1	In Data Source Selection, select the JDBC data source to use.

2	In Data Set Type, select SQL Stored Procedure Query.

3	In Data Set Name, type a name for the data set. Choose Next.

Query displays a template for executing a stored procedure, as shown in Figure 3‑3.

In Available Items, navigate to the stored procedure. Select the stored procedure, and drag it to the text area. The stored procedure name appears at the insertion point. In the text area, type the required information to execute the stored procedure. For example, you should include any arguments that are passed to the stored procedure.

To type the stored procedure, enclose the call statement in left and right braces, for example:

{call getTable('ClassicModels.Customers')}

{call getClientOrders('103')}

If you type the stored procedure without the braces, BIRT treats the statement as a regular RDBMS call, so execution depends on the RDBMS of your data source.

4	Choose Finish to save the data set. Edit Data Set displays the columns returned by the stored procedure, and provides options for editing the data set.
