Question regarding cursor variables, while using table functions

Question

Hi,
I created a procedure and when i'm try'g to call it. now i'm getting this error.
CREATE OR REPLACE TYPE TAB_EMP_REC IS OBJECT(
EMP_ID NUMBER(9),
EMP_NAME VARCHAR2(30));
CREATE OR REPLACE TYPE T_EMP_TMP IS TABLE OF TAB_EMP_REC ;
CREATE OR REPLACE PROCEDURE USP_CREATE_DATA(
p_Input IN NUMBER,
V_EMP_CUR OUT sys_refcursor) IS
T_EMp T_EMP_TMP := T_EMP_TMP( );
BEGIN
t_emp.extend();
t_emp(1) := TAB_EMP_REC(p_input, 'jack');
OPEN V_EMP_CUR FOR SELECT * from TABLE(t_emp);
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('ERROR '||SQLERRM);
END USP_CREATE_DATA;
calling procedure::
DECLARE
type O_RESULT_CUR is ref cursor return TAB_EMP_REC;
V_EMP_REC TAB_EMP_REC;
BEGIN
USP_CREATE_DATA(99, O_RESULT_CUR);
LOOP
FETCH O_RESULT_CUR INTO V_EMP_REC;
EXIT WHEN O_RESULT_CUR%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(V_EMP_REC.EMP_ID);
END LOOP;
CLOSE O_RESULT_CUR;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('ERROR '||SQLERRM);
END;
Now i'm getting an error PLS-00362: invalid cursor return type; 'TAB_EMP_REC' must be a record type.
My question is i already declared it as a database object. What do i need to do ?
thank you

Answer 1

but t_emp(1) := TAB_EMP_REC(p_input, 'jai');
is correct, since.. i'm passing a record into t_emp(1)(this is the first column in this table)No it is not, since TAB_EMP_REC is just an object, when used as a collection, it can be a VARRAY, a PL/SQL table(associative array), nested table etc. As mentioned in my earlier post, if you want to use a collection of the same structure (with subscript n, as you have done here), then you need to declare a collection of type TAB_EMP_REC.In this case you have already declared a table of type TAB_EMP_REC - +CREATE OR REPLACE TYPE T_EMP_TMP IS TABLE Also, t_emp is of type T_EMP_TMP - T_EMp T_EMP_TMP := T_EMP_TMP( );*
As for the error you are getting, try changing to -
t_emp := T_EMP_TMP(TAB_EMP_REC(p_input, 'jai'));*
