Question : Return Ref

I have following cursor which accepts the partition name as input parameter.
I want return the values as refcursor and want to lock those records which are selected.

Can I get some help how to perform this process using PLSQL.

I have written sample SP which just provides out lines. Can I get some help to rewrite this SP to work.

Thanks

          CREATE OR REPLACE PROCEDURE C_PUT

 p_dat_no number

 FOR UPDATE SKIP LOCKER;'
 
BEGIN

IF CUR%ROWCOUNT > 0 THEN
DBMS_OUTPUT.PUT_LINE('There are rows to process');
RETURN as Refcursor
Else
DBMS_OUTPUT.PUT_LINE('NO rows to process');

Answer : Return Ref

What about this. You can update the table without changing anything.

CREATE OR REPLACE PROCEDURE C_PUT
(p_partition_name in varchar2,
p_dat_no number
r_ref out sys_refcursor)
CURSOR CUR IS
SELECT PAT_NO, PNAME, OT_P
FORM TARGET.PATENTS partition ('||p_partition_name||')
WHERE DAT_NO = p_dat_no
ORDER BY PAT_NO;

BEGIN
----- modification
update TARGET.PATENTS partition ('||p_partition_name||')
set PAT_NO = PAT_NO
WHERE DAT_NO = p_dat_no;

IF CUR%ROWCOUNT > 0 THEN
DBMS_OUTPUT.PUT_LINE('There are rows to process');
RETURN as Refcursor
Else
DBMS_OUTPUT.PUT_LINE('NO rows to process');
END IF;

END;
