Testing/Running the stored procedure(has OUT params) in Oracle sqldeveloper or sqlplus

sql>var v_result numbersql>exec sp_isauthorized('a', 'b', :v_result)PL/SQL procedure successfully completed.sql>print v_result -- or turn autoprint on===================================================To test the stored procedure, we can either execute it from within an environment that allows you to execute stored procedures and supply their parameters, such as SQL Navigator or Toad, or we can run it from within sqlplus.Executing a stored procedure from within sqlplus is straightforward once you know how.Firstly, start up sqlplus and declare a sqlplus variable of type refcursor. This declares a sqlplus variable of type refcursor (a sqlplus type), called "results":SQL> var results refcursorNext, execute the procedure, supplying a number as a parameter, and assigning the result into our variable, "results". Note the unusual syntax.SQL> exec :results := sp_get_stocks(20.0)PL/SQL procedure successfully completed.Finally, use the sqlplus print statement to print out the result setSQL> print resultsRIC PRICE UPDATED------ --------- ---------AMZN 15.5 21-OCT-01SUNW 16.25 21-OCT-01ORCL 14.5 21-OCT-01If this works successfully, similar to the above, the stored procedure (well, function) is working correctly.

if(cs==null)
cs=m_Conn.prepareCall("{call p(?,?)}");
cs.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);
cs.setString(2,column);
cs.execute();
rs=(ResultSet)cs.getObject(1);
while(rs.next()){
System.out.println(column+"="+rs.getString(1));
}
rs.close();
rs=null;
