Answer 1

you can go for a dynamic query ;)
create or replace
FUNCTION TEST_SSK
        p_srot  number
RETURN SYS_REFCURSOR
AS
C_testssk SYS_REFCURSOR;
l_str VARCHAR2(4000);
l_order VARCHAR2(100);
BEGIN
l_str := 'SELECT LOAN_CODE,LOAN_DATE,DUE_DATE,LOAN_AMT FROM LOAN_MASTER ';
IF p_sort = 'LC'
THEN
  l_order := ' ORDER BY LOAN_CODE ';
ELSIF p_sort = 'LD'
THEN
  l_order := ' ORDER BY LOAN_DATE ';
END IF;
  l_str := l_str || l_order ;
OPEN C_TESTSSK FOR l_str;
return C_testssk;
end;
