Introduction

This example demonstrates using a JDBC driver to call a stored procedure from MySQL. The Stored procedure takes two arguments. One is an input parameter and specifies what product name the stored procedure is executed for and returns the number of orders that included the given product. The second parameter is an output parameter and returns the count of total orders.
Add comments at the bottom of the example.


BIRT Version Compatibility

This example was created and tested wit BIRT 2.1.1. It should also be compatible with newer versions of BIRT.

Description

In order to use this example, you will first need to have the Classic Models Database installed on MySQL. This example database is available here. Once this database is loaded you will then need to create the stored procedure used in the reprot. The source for the procedure is below.

Stored Procedure SQL

CREATE PROCEDURE OrdersByProductProc (IN Product varchar(50), OUT test int   )
BEGIN

SELECT count(*), productName FROM orderdetails, products WHERE orderdetails.productCode = products.productCode AND products.productName = Product GROUP BY   products.productName;
Select Count(*) INTO test FROM orderdetails;
END
GO

Once the procedure is created, it can be called by using the following statement in the Data Set Editor for an SQL Stored Procedure Query.

{call OrdersByProductProc (?, ?)}

The first ? refers to the input parameter and the second ? refers to the output parameter. See the dataset parameters in the Data Set editor.

The example uses one data set to populate a dynamic report parameter that is then passed to the second data set, which contains the stored procedure. The results of the stored procedure are presented in a table element. In the table footer the output parameter of the stored procedure is referenced as follows:

"Total Orders: " + outputParams["totalorders"]
