Re: What an error message...

Just a guess.

The Parameter-Type-Name (in your case IN) is only written once at the
beginning of your vars. The doc seems to hint that you need to state
IN or OUT for each variable.


CREATE PROCEDURE Enrollstudent(in :Stud_id integer, in :Class_Id
integer, IN :GPA REAL);
BEGIN
INSERT INTO Enrolls VALUES(:Stud_id, :Class_id, :GPA);

END;
