MySQL error You have an error in your SQL syntax check the manual that corresponds to your MySQL server version for the right syntax to use near

Question

This is my Stored procedure :

CREATE PROCEDURE ProG()
  BEGIN
    SELECT * FROM `hs_hr_employee_leave_quota`;
  END

But I get this error:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3

What does the mistake signify? Why is line number two problematic?
