TOAD displaying cursor recordset returned by stored procedure - plsql

Question

How I could print recorset result from the returning cursor, please.
Down below executes fine but I need to see result.
This is block in TOAD, calling package sp AMD_NEEDMSG:
DECLARE
RETURN_RECORDSET CTI_MATRIX.AMD.REF_CURSOR;
BEGIN
CTI_MATRIX.AMD.AMD_NEEDMSG ( '88888888885', RETURN_RECORDSET );
END;
This package spec:
CREATE OR REPLACE PACKAGE CTI_MATRIX.AMD AS
TYPE REF_CURSOR IS REF CURSOR;
PROCEDURE AMD_NEEDMSG (v_CRN IN VARCHAR2, return_recordset OUT REF_CURSOR);
END AMD;
This is package body:
CREATE OR REPLACE PACKAGE BODY CTI_MATRIX.AMD AS
PROCEDURE AMD_NEEDMSG (v_CRN IN VARCHAR2, return_recordset OUT REF_CURSOR) IS
return_flag INTEGER;
row_cnt INTEGER;
number_of_days INTEGER;
var_DATE DATE;
CURSOR ACCNTSEARCH (P_CRN IN VARCHAR2) IS
SELECT DISTINCT COUNT(*) , AMD.MSG_DATE
FROM TBL_AMD_NEEDMSG AMD
WHERE AMD.PHONE_NUMBER = P_CRN AND ROWNUM = 1;
BEGIN
OPEN ACCNTSEARCH(v_CRN);
FETCH ACCNTSEARCH INTO row_cnt, var_DATE;
CLOSE ACCNTSEARCH;
IF (row_cnt = 0)
THEN
INSERT INTO TBL_AMD_NEEDMSG (PHONE_NUMBER, MSG_DATE) VALUES (v_CRN , SYSDATE);
return_flag := 1;
ELSE
SELECT SYSDATE-var_DATE INTO number_of_days FROM dual;
IF (number_of_days>7)
THEN
UPDATE TBL_AMD_NEEDMSG SET MSG_DATE = SYSDATE WHERE PHONE_NUMBER = v_CRN;
return_flag := 1;
ELSE
return_flag := 0;
END IF;
END IF;
COMMIT;
OPEN return_recordset FOR
SELECT return_flag AS ReturnFLag FROM DUAL;
EXCEPTION
WHEN OTHERS THEN
ROLLBACK;
END AMD_NEEDMSG;
END AMD;
/
Bottom line is to return to client a value of return_flag in the form of record set.

Answer 1

To return the return_flag, which is int=1 or 0 you need function that returns a single value, not recordset. Below are general recordset examples - hope this helps:
DECLARE
TYPE empcurtyp IS REF CURSOR;
emp_cv empcurtyp;
--
TYPE namelist IS TABLE OF scott.emp.ename%TYPE;
TYPE sallist IS TABLE OF scott.emp.sal%TYPE;
names namelist;
sals sallist;
BEGIN
OPEN emp_cv FOR
SELECT ename, sal FROM scott.emp
WHERE job = 'MANAGER' ORDER BY sal DESC;
--
FETCH emp_cv BULK COLLECT INTO names, sals;
CLOSE emp_cv;
-- loop through the names and sals collections
FOR i IN names.FIRST .. names.LAST LOOP
DBMS_OUTPUT.PUT_LINE
('Name = ' || names(i) || ', salary = ' || sals(i));
END LOOP;
END;

-- SYS_REFCURSOR example --
DECLARE
p_rc_type SYS_REFCURSOR;
emp_rec scott.emp%ROWTYPE;
--
PROCEDURE p_Emp_Info (p_cur_var OUT SYS_REFCURSOR)
IS
BEGIN
OPEN p_cur_var FOR
SELECT ename, job FROM scott.emp WHERE job = 'MANAGER';
LOOP
FETCH p_cur_var INTO emp_rec.ename, emp_rec.job;
EXIT WHEN p_cur_var%NOTFOUND;
dbms_output.put_line(emp_rec.ename ||' '|| emp_rec.job);
END LOOP;
CLOSE p_cur_var;
END p_Emp_Info;
--
BEGIN
p_Emp_Info(p_rc_type);
END;
