Example 2: Stored Procedures Declared and Defined in a Package and Package Body

This topic provides an example of a stored procedure declared and defined in a package and package body.

Suppose that an Oracle stored procedure is defined as:

CREATE OR REPLACE PACKAGE DEMO_PKG AS
type curtype is ref cursor;
PROCEDURE empquery_proc(p_job in varchar2, cur OUT DEMO_PKG.curtype);
end DEMO_PKG ;
CREATE OR REPLACE PACKAGE BODY DEMO_PKG AS
PROCEDURE empquery_proc(p_job in varchar2, cur OUT DEMO_PKG.curtype) AS
lcur DEMO_PKG.curtype;
begin
  open lcur for
  select * from EMP WHERE JOB = p_job;
  cur:=lcur;
end empquery_proc;
end DEMO_PKG;

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

1. Start Logi JReport Designer and open an existing catalog.
2. In the Catalog Manager, right-click the data source 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 Parameter 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_proc&SQL={call demo_pkg.empquery_proc(?,?)}&REFCURSORINDEX=2&PARAMVALUE="SALESMAN"
   • DRIVER=oracle.jdbc.driver.OracleDriver&URL="jdbc:oracle:thin:@<hostname>:1521:oracle8"&USER=scott&PSWD=tiger&
OWNER=SCOTT&PROCNAME=empquery_proc&SQL={call demo_pkg.empquery_proc(?,?)}&REFCURSORINDEX=2&INPARAMVALUE="SALESMAN",varchar,1
   • OWNER=SCOTT&PROCNAME=empquery_proc&SQL={call demo_pkg.empquery_proc(?,?)}&REFCURSORINDEX=2&PARAMVALUE="SALESMAN"
   • OWNER=SCOTT&PROCNAME=empquery_proc&SQL={call demo_pkg.empquery_proc(?,?)}&REFCURSORINDEX=2&INPARAMVALUE="SALESMAN",varchar,1

   

6. Select the OK button. The UDS class will then be added into the catalog.
