Hey Guys, I need some help here

Question

Im doing some create view and create procedures for my work.
In creating view, its just done perfectly.
However with create procedures work, I got some problem with the result.
So here is the coding:
create or replace
PROCEDURE "USP_EDW_CASH_MARGIN"
result_cursor          OUT     TYPES.cursor_type
AS
CURSOR v_cursor IS
SELECT
to_char (CM100,'99999999999999.99'),
to_char (CM101,'99999999999999.99'),
to_char (CM200,'99999999999999.99'),
to_char (CM300,'99999999999999.99'),
to_char (CM301,'99999999999999.99'),
to_char (CM310,'99999999999999.99'),
to_char (CM320,'99999999999999.99'),
to_char (CM400,'99999999999999.99'),
to_char (CM401,'99999999999999.99'),
to_char (CM402,'99999999999999.99'),
to_char (CM500,'99999999999999.99'),
to_char (CM720,'99999999999999.99'),
to_char (CM730,'99999999999999.99'),
to_char (CM740,'99999999999999.99'),
to_char (CM999,'99999999999999.99')
FROM VW_CASH_MARGIN a;
v_id varchar2(100);
v_row varchar2(4000);
v_clob CLOB;
v_buffer varchar2(10000);
BEGIN
v_id := 'EDW_CASH_MARGIN';
DELETE FROM TBL_INTERFACE_DATA WHERE cd = v_id;
INSERT INTO TBL_INTERFACE_DATA (CD,INT_DATA,DT_CREATED)
VALUES (v_id,EMPTY_CLOB(),(SELECT CURR_PROC_DATE FROM TBL_PROC_DATE));
SELECT INT_DATA INTO v_clob
FROM TBL_INTERFACE_DATA
WHERE CD = v_id
FOR UPDATE;
OPEN v_cursor;
v_buffer := '';
dbms_output.put_line(LENGTH(v_buffer));
LOOP
FETCH v_cursor INTO v_row;
EXIT WHEN v_cursor%NOTFOUND;
if (length(v_buffer) + length(v_row)) < 10000 or v_buffer is null then
v_buffer := v_buffer || v_row;
else
DBMS_LOB.WRITEAPPEND(v_clob, LENGTH(v_buffer), v_buffer);
v_buffer := v_row;
end if;
END LOOP;
if LENGTH(v_buffer) > 0 then
DBMS_LOB.WRITEAPPEND(v_clob, LENGTH(v_buffer)-1, v_buffer);
end if;
CLOSE v_cursor;
OPEN result_cursor FOR
SELECT 'success' AS status FROM dual;
END;
After i run this coding.
I got these errors :
1)Error(46,5): PL/SQL: SQL Statement ignored.
2)Error(46,5): PLS-00394: wrong number of values in the INTO list of a FETCH statement
It says that the error is with this code "FETCH v_cursor INTO v_row;"
Can someone please help me.

Answer 1

ok let me explain with emp table.
DECLARE
CURSOR c IS SELECT ename,sal FROM emp;
v_ename VARCHAR2(2000);
BEGIN
OPEN c;
LOOP
FETCH c INTO v_ename;
EXIT WHEN c%NOTFOUND;
Dbms_Output.put_line(v_name);
END LOOP;
CLOSE c;
END;Here i'm selecting 2 columns in the cursor and getting into one variable.
So i'm getting error like this
ORA-06550: line 7, column 1:
PLS-00394: wrong number of values in the INTO list of a FETCH statement
ORA-06550: line 7, column 1:
PL/SQL: SQL Statement ignored
DECLARE
CURSOR c IS SELECT ename,sal FROM emp;
v_ename VARCHAR2(2000);
v_sal NUMBER(10);
BEGIN
OPEN c;
LOOP
FETCH c INTO v_ename,v_sal;
EXIT WHEN c%NOTFOUND;
Dbms_Output.put_line(v_ename||v_sal);
END LOOP;
CLOSE c;
END;Here i'm selecting 2 columns in the cursor and getting into two different variables.so no error.
DECLARE
CURSOR c IS SELECT ename,sal FROM emp;
v_row c%rowtype; -->record type declaration
BEGIN
OPEN c;
LOOP
FETCH c INTO v_row;
EXIT WHEN c%NOTFOUND;
Dbms_Output.put_line(v_row.ename||v_row.sal);---> Here i'm mentioning which column to be printed
END LOOP;
CLOSE c;
END;Same thing i'm getting all columns variable into the records so no error.
