In SQL a query within a function works but not in PL/SQL.

Example:
********
SQL:
SELECT to_char((SELECT sysdate FROM dual), 'DD/MM/YYYY') FROM dual;

This SQL works properly.

PL/SQL:
DECLARE
var VARCHAR2(20);
BEGIN
SELECT to_char((SELECT SYSDATE FROM dual))
INTO var
FROM dual;
END;
/

This PL/SQL doesnot work. It gives an error.

WHY? And how can I overcome it?

Try this

DECLARE
var VARCHAR2(20);
BEGIN
SELECT to_char(d.d, 'DD/MM/YYYY') into var
FROM (SELECT sysdate d FROM dual) d;
dbms_output.put_line(var);
END;
