Example 1: Stored Procedures Defined Outside of a Package

Suppose that an Oracle stored procedure is defined as:

CREATE OR REPLACE PACKAGE SHDEMO as
type curtype is ref cursor;
END SHDEMO;
CREATE OR REPLACE PROCEDURE empquery (p_job in varchar2, cur OUT SHDEMO.curtype) as
lcur SHDEMO.curtype;
begin
  open lcur for
  select * from EMP WHERE JOB = p_job;
  cur:=lcur;
END empquery;

To add the stored procedure into a JReport catalog, follow the steps below:

1. Start JReport Designer and open an existing catalog.
2. In the Catalog Manager, right-click the data source node to which the stored procedure is to be added, then select New User Defined Data Source. The New User Defined Data Source dialog appears.
3. In the Name field, specify a name for the UDS, for example, UDS1.
4. In the Class Name field, input the UDS class jet.datasource.oracle.OracleProcedureUDS.
5. In the Parameters box, enter one of the following:
   • DRIVER=oracle.jdbc.driver.OracleDriver&URL="jdbc:oracle:thin:@<hostname>:1521:oracle8"&USER=scott&PSWD=tiger&
OWNER=SCOTT&PROCNAME=empquery&SQL={call empquery(?,?)}&REFCURSORINDEX=2&PARAMVALUE="SALESMAN"
   • DRIVER=oracle.jdbc.driver.OracleDriver&URL="jdbc:oracle:thin:@<hostname>:1521:oracle8"&USER=scott&PSWD=tiger&
OWNER=SCOTT&PROCNAME=empquery&SQL={call empquery(?,?)}&REFCURSORINDEX=2&INPARAMVALUE="SALESMAN",varchar,1
   • OWNER=SCOTT&PROCNAME=empquery&SQL={call empquery(?,?)}&REFCURSORINDEX=2&PARAMVALUE="SALESMAN"
   • OWNER=SCOTT&PROCNAME=empquery&SQL={call empquery(?,?)}&REFCURSORINDEX=2&INPARAMVALUE="SALESMAN",varchar,1

   

6. Click the OK button, and the UDS class will then be added into the catalog.
