ORA-06553: PLS-801:Internal Error [55018] - sql

Question

I want to make a function call like SELECT URUN_GETIR('test1') FROM DUAL; but i got ORA-06553: PLS-801: Internal Error [55018].
I tried ORA-06553: PLS-801: internal error [55018] when testing function returning ROWTYPE this like for ex URUN_GETIR('test1').KULUSERNAME but getting same error. It didn't work for me.Thanks in advance.
My db table :
My plsql function code :
create or replace FUNCTION URUN_GETIR(KULADI VARCHAR2)
RETURN URUN%ROWTYPE
AS
URUN_TABLO URUN%ROWTYPE;
BEGIN
SELECT * INTO URUN_TABLO FROM URUN ur WHERE ur.kulusername = KULADI;
RETURN URUN_TABLO;
END;

You can achieve your goal with using table functions. Other than that you can not call directly your function like you wanted. Here is another choice for you Use Stackoverflow Wisely
CREATE TABLE URUN
(
CREATED_BY VARCHAR2 (50 CHAR),
CREATED_DATE DATE,
UPDATED_BY VARCHAR2 (50 CHAR),
KULUSERNAME VARCHAR2 (50 CHAR),
ID NUMBER (10)
);
INSERT INTO URUN (CREATED_BY, CREATED_DATE, UPDATED_BY, KULUSERNAME, ID) VALUES('TEST1',TO_DATE('19000101','YYYYMMDD') ,'TTEST1','USER1',1);COMMIT;
INSERT INTO URUN (CREATED_BY, CREATED_DATE, UPDATED_BY, KULUSERNAME, ID) VALUES('TEST2',TO_DATE('19000102','YYYYMMDD') ,'TTEST2','USER2',2);COMMIT;
INSERT INTO URUN (CREATED_BY, CREATED_DATE, UPDATED_BY, KULUSERNAME, ID) VALUES('TEST3',TO_DATE('19000103','YYYYMMDD') ,'TTEST3','USER3',3);COMMIT;
INSERT INTO URUN (CREATED_BY, CREATED_DATE, UPDATED_BY, KULUSERNAME, ID) VALUES('TEST4',TO_DATE('19000104','YYYYMMDD') ,'TTEST4','USER4',4);COMMIT;
CREATE OR REPLACE TYPE URUN_OBJ AS OBJECT
(
CREATED_BY VARCHAR2 (50 CHAR),
CREATED_DATE DATE,
UPDATED_BY VARCHAR2 (50 CHAR),
KULUSERNAME VARCHAR2 (50 CHAR),
ID NUMBER (10)
);
CREATE OR REPLACE TYPE URUN_OBJ_TAB AS TABLE OF URUN_OBJ;
CREATE OR REPLACE FUNCTION URUN_GETIR (KULADI IN VARCHAR2)
RETURN URUN_OBJ_TAB
PIPELINED
AS
REC_OBJ URUN_OBJ;
CURSOR DATA
IS
SELECT *
FROM URUN UR
WHERE UR.KULUSERNAME = KULADI;
BEGIN
FOR REC IN DATA
LOOP
REC_OBJ :=
URUN_OBJ (REC.CREATED_BY,
REC.CREATED_DATE,
REC.UPDATED_BY,
REC.KULUSERNAME,
REC.ID);
PIPE ROW (REC_OBJ);
END LOOP;
RETURN;
END;
