I have just created a PL/SQL user-defined function called Calc_Grade and is trying to figure out which of the 4 statement will successfully test it
EXECUTE calc_grade;
EXECUTE calc_grade(SELECT grade FROM grade_book);
SELECT * FROM calc_grade(grade);
SELECT calc_grade(grade) FROM grade_book;
Can someone please help me out.
Thanks

Try the fourth.
The first two will fail (this is a function, it returns something while EXECUTE is for Procedures). You could wrap it in a call to dbms_output.put_line, which results in the following (don't forget to set the serveroutput on):EXECUTE <B>Dbms_Output.Put_Line(</B>calc_grade(parameter?)<B>)</B>
The third won't work either.
