Question

I’m trying to call an Oracle stored proc using SQL Developer. The proc outputs results using a sys_refcursor. I right click in the proc window which brings up the Run PL/SQL window. When I choose the proc I want it creates all the input params etc for me. Below is the code I’m using to try and loop through the sys_refcursor and output the results, but I’m getting an error on the ‘v_rec v_Return%rowtype;’ line :

ORA-06550: line 6 column 9:
PLS-00320: the declaration of the type of this expression is incomplete or malformed.
ORA-06550: line 6 column 9:
PL/SQL: Item ignored

vendor code 6550

I found the looping code on a couple of other websites and it seems to be the way to do it but it’s not working for me no matter what I try. Another question – on the DBMS_OUTPUT.PUT_LINE(‘name = ‘ || v_rec.ADM) am I referencing the v_rec correctly i.e. is v_rec.”column_name” the correct way??

I’m not that used to Oracle and have never used SQL plus. Any suggestions appreciated.

DECLARE
  P_CAE_SEC_ID_N NUMBER;
  P_PAGE_INDEX NUMBER;
  P_PAGE_SIZE NUMBER;
  v_Return sys_refcursor;
  v_rec v_Return%rowtype;
BEGIN
  P_CAE_SEC_ID_N := NULL;
  P_PAGE_INDEX := 0;
  P_PAGE_SIZE := 25;

  CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
    P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
    P_PAGE_INDEX => P_PAGE_INDEX,
    P_PAGE_SIZE => P_PAGE_SIZE,
    P_FOF_SEC_REFCUR => v_Return
  );
  -- Modify the code to output the variable
  -- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
  loop
    fetch v_Return into v_rec;
    exit when v_Return%notfound;
    DBMS_OUTPUT.PUT_LINE('name = ' || v_rec.ADM);
  end loop;

END;

Your problem is here:

v_Return sys_refcursor;
v_rec v_Return%rowtype;

v_Return is a cursor variable and has no specific structure (list of columns), so v_Return%rowtype is not a valid record structure to declare v_rec. It is even possible for different calls to the procedure to return cursors with different structures.

You know what you are expecting the structure of the returned cursor to be (but Oracle doesn’t) so you need to explicitly define the appropriate record structure e.g.

type t_row is record (empno number, ename varchar2(30));
v_rec t_row;
