I want to fetch limited no. of rows using refcursor
. then I need to update same set of records. is it possible?
create or replace PROCEDURE myproc (
P_ROWCOUNT IN NUMBER,
OUT_TXN_IDS OUT OF_CR_TYPE,
P_CD_ERROR OUT NUMBER,
P_DS_ERROR OUT VARCHAR2
)
AS
V_TXNID NUMBER;
BEGIN
P_CD_ERROR := 0;
P_DS_ERROR := 'SUCCESS';
OPEN OUT_TXN_IDS for
SELECT id FROM table1 WHERE status='N' AND ROWNUM<=P_ROWCOUNT;
EXCEPTION
WHEN OTHERS THEN
P_CD_ERROR := sqlcode;
P_DS_ERROR := 'WF-ERROR - myproc - ' || substr(SQLERRM, 1, 200);
RETURN;
END myproc;
I need to update same records to status Y after refcursor
returns. can we do this. please suggest
I don't have your tables nor data so I simplified it a little bit, but - it should work nonetheless.
Initial statuses:
SQL> SELECT status, count(*) FROM table1 group by status;
S COUNT(*)
- ----------
Y 7
N 7
Procedure: basically, you'd modify rows represented by ID
returned by ref cursor.
SQL> DECLARE
2 out_txn_ids SYS_REFCURSOR;
3 p_rowcount NUMBER := 5;
4 l_id table1.id%TYPE;
5 BEGIN
6 OPEN out_txn_ids FOR SELECT id
7 FROM table1
8 WHERE status = 'N'
9 AND ROWNUM <= p_rowcount;
10
11 LOOP
12 FETCH out_txn_ids INTO l_id;
13
14 EXIT WHEN out_txn_ids%NOTFOUND;
15
16 UPDATE table1
17 SET status = 'Y'
18 WHERE id = l_id;
19 END LOOP;
20
21 CLOSE out_txn_ids;
22 END;
23 /

Result:
