Question

ORA-06553: PLS-306 Error when Calling a Stored Procedure with sys_refcursor

Asked by: CDL2

I am trying to build a stored procedure where the output will become the datasource for Crystal Reports.  I was trying to follow guidance provided in the article "Using Ref Cursors To Return Recordsets" http://www.oracle-base.com/articles/misc/UsingRefCursorsToReturnRecordsets.php, which was referenced on another post in EE.

Per the instructions I skipped step one (create the package) since I am using Oracle 10gR2.  I used sys_refcursor, which is supposedly already defined.

I get a clean compile, but when I try to call the procedure (through TOAD) I get the error "ORA-06553: PLS-306: wrong number or types of arguments in call to 'RPT730'".  I don't know if it makes a difference, but testapp730 in the FROM-clause is a view, not a table.

Any suggestions would be appreciate.

--  Stored Procedure
CREATE OR REPLACE PROCEDURE TESTAPP.RPT730 (
     p_type      IN VARCHAR2,      
     p_year      IN VARCHAR2,
     p_acctper   IN VARCHAR2,
     p_billno    IN VARCHAR2, 
     p_dov       IN VARCHAR2,
     p_refno     IN NUMBER,
     p_cursor    OUT sys_refcursor
    ) IS
BEGIN
    OPEN p_cursor FOR 
        SELECT  *          
        FROM    testapp730
        WHERE   ref_no in  (SELECT  ref_no
                            FROM    testapp730            
                            WHERE   acct_fy = p_year
                            )
        ORDER BY acct_fy, acct_period, ref_no, rcd_type, def_seq_no, def_doc_suffix;
END; 
/         
 
--   Call Stored Procedure
CALL TESTAPP.RPT730('fyap', '2009', '10', '', '', 0);

>>CALL TESTAPP.RPT730('fyap', '2009', '10', '', '', 0);

There is no ref cursor passed into your procedure. The procedure expects its last argument to have one.

I prefer to return ref cursors from a function like so:

CREATE OR REPLACE FUNCTION getall RETURN SYS_REFCURSOR
IS
  result SYS_REFCURSOR;
BEGIN
  open result for select * from t;
  return result;
END;
/


That way you can either use it in a SQL statement:

select getall from dual;

Or use it in a PL/SQL block as the target of an assign. It is more clear to me that way.

c1 := getall();

In Crystal reports, how can you pass in a ref cursor parameter? I don't know Crystal Reports, but in PL/SQL it would be thus to call your procedure as is:


DECLARE
  RES SYS_REFCURSOR; -- declare a variable of ref cursor type
BEGIN
  --   Call Stored Procedure
  TESTAPP.RPT730('fyap', '2009', '10', '', '', 0, RES);
  -- Now RES has the cursor
END;
/

The cursor is not an input, it is the output of the procedure that gets passed to Crystal.  It is the
datasource that Crystal will use to generate the report.  That's why I'm not sure how to pass anything for that variable to the procedure.

I don't think that Crystal will accept a function as a datasource.  It will accept a stored procedure.

 

by: mrjoltcolaPosted on 2009-07-27 at 12:43:15ID: 24955173

OUT parameters are still parameters. You did not provide one in your above sample. It is not an implicit parameter and must be listed.

 

by: mrjoltcolaPosted on 2009-07-27 at 12:47:23ID: 24955232

If Crystal will not accept a function as a datasource, try it as a query, using a function that returns the result set, as my sample shows.

"select myfunc from dual"

 

by: CDL2Posted on 2009-07-27 at 13:59:17ID: 24955964

Well, the procedure isn't erring off.  Now I just have to get it to show me the results.

 

by: mrjoltcolaPosted on 2009-07-27 at 15:17:42ID: 24956484

If you use the function version then you simply treat it the same as a query with a result set. ("select myfunc from dual")

 

by: CDL2Posted on 2009-07-29 at 09:18:54ID: 31608397

Thanks.  Solution gave a clean compile (although I still can't see what shows up in the result cursor).

 

by: mrjoltcolaPosted on 2009-07-29 at 10:00:32ID: 24972169

Test the function from sqlplus and see what you get.

 

by: CDL2Posted on 2009-07-29 at 11:01:09ID: 24972793

I get data back if I execute the function in sqlplus.  That helps a little since I can use the same basic code between the begin-end, although I have to change the variable section some.  Also, I can't use the function as a datasource to Crystal Reports, so I still have to be able to test the stored procedure.

Thanks for you help.  You did explain what I needed to do with the OUT variable of sys_refcursor!!!
