Question

I am using Oracle SQL Developer, but I am having an issue seeing results from a package that returns a ref cursor. Below is the package definition:

CREATE OR REPLACE package instance.lswkt_chgoff_recov
as
      type rec_type is record
            (
            source_cd                       lswk_tpr.gltrans.tpr_source_cd%TYPE,
            as_of_dt                        lswk_tpr.gltrans.tpr_as_of_dt%TYPE,
            chrg_off_recov                  varchar2(5),
            process_dt                      lswk_tpr.gltrans.dtgltran%TYPE,
            effect_dt                       lswk_tpr.gltrans.dtgltran%TYPE,
            account_nbr                     lswk_tpr.contract.lcontid%TYPE,
            naics_cd                        lswk_tpr.udfdata.sdata%TYPE,
            prod_type                       varchar2(20),
            off_nbr                         lswk_tpr.schedule.sctrcdty%TYPE,
            borrower_nm                     lswk_tpr.customer.scustnm%TYPE,
            tran_type_cd                    lswk_tpr.gltrans.sglcd%TYPE,
            tran_type_desc                  lswk_tpr.gltrans.sglcd%TYPE,
            tran_amt                        lswk_tpr.gltrans.ctranamt%TYPE,
            note_dt                         lswk_tpr.schedule.dtbk%TYPE,
            accru_cd                        number,
            non_accr_cd                     lswk_tpr.schedule.dtlstincsus%TYPE,
            comm_sb_ind                     varchar2(4)
            );

      type cur_type is ref cursor return rec_type;

      procedure sp
            (
            p_as_of_dt              in      date,
            ref_cur                 in out  cur_type
            );
end;
/

I guess the question is this possible and if so, what do I need to do. I am using Oracle SQL Developer 1.5.5. Thanks.

Here is the code I used to call my package (generated by TOAD):

DECLARE 
  P_AS_OF_DT DATE;
  REF_CUR instance.LSWKT_CHGOFF_RECOV.CUR_TYPE;
  REF_CUR_row REF_CUR%ROWTYPE;

BEGIN 
  P_AS_OF_DT := '31-AUG-2009';

  instance.LSWKT_CHGOFF_RECOV.SP ( P_AS_OF_DT, REF_CUR );

  DBMS_OUTPUT.Put_Line('REF_CUR =');
  IF REF_CUR%ISOPEN THEN
  DBMS_OUTPUT.Put_Line('  SOURCE_CD  AS_OF_DT  CHRG_OFF_RECOV  PROCESS_DT  EFFECT_DT  ACCOUNT_NBR  NAICS_CD  PROD_TYPE  OFF_NBR  BORROWER_NM  TRAN_TYPE_CD  TRAN_TYPE_DESC  TRAN_AMT  NOTE_DT  ACCRU_CD  NON_ACCR_CD  COMM_SB_IND');
    LOOP
      FETCH REF_CUR INTO REF_CUR_row;
      EXIT WHEN REF_CUR%NOTFOUND;
      DBMS_OUTPUT.Put_Line(
           '  ' || '[TPR_SOURCE_CD%type]'
        || '  ' || '[TPR_AS_OF_DT%type]'
        || '  ' || '''' || REF_CUR_row.CHRG_OFF_RECOV || ''''
        || '  ' || '[DTGLTRAN%type]'
        || '  ' || '[DTGLTRAN%type]'
        || '  ' || '[LCONTID%type]'
        || '  ' || '[SDATA%type]'
        || '  ' || '''' || REF_CUR_row.PROD_TYPE || ''''
        || '  ' || '[SCTRCDTY%type]'
        || '  ' || '[SCUSTNM%type]'
        || '  ' || '[SGLCD%type]'
        || '  ' || '[SGLCD%type]'
        || '  ' || '[CTRANAMT%type]'
        || '  ' || '[DTBK%type]'
        || '  ' || NVL(TO_CHAR(REF_CUR_row.ACCRU_CD), 'NULL')
        || '  ' || '[DTLSTINCSUS%type]'
        || '  ' || '''' || REF_CUR_row.COMM_SB_IND || '''');
    END LOOP;
  ELSE
    DBMS_OUTPUT.Put_line('  (Ref Cursor is closed)');
  END IF;


  COMMIT; 
END;

I get the error:

ORA-06502: PL/SQL: numeric or value error

Hope this clears it up a bit more.

You can easily print the output results of a ref_cursor in SQL Developer to see the return value..

Here’s an example of a Refcursor Function:

create or replace function get_employees() return sys_refcursor as
  ret_cursor sys_refcursor;
begin
  open ret_cursor for
    select * from employees;
  return ret_cursor; 
end get_employees;

Quick and dirty method:

select get_employees() from dual; 

Neat and tidy method:

variable v_ref_cursor refcursor;
exec :v_ref_cursor := get_employees(); 
print :v_ref_cursor
