Solution 1

The problem is there is no data type named - SMALLIN

Try something like this it should work for you.

CREATE TABLE Course
(Cno CHAR(4) PRIMARY KEY,
Cname CHAR(40),
Cpno CHAR(4) REFERENCES Course(Cno),
Ccredit int,
);

Solution 2

Try this. I guess it should work.

SQL

CREATE TABLE Course
 (Cno CHAR(4) PRIMARY KEY,
 Cname CHAR(40),
 Cpno CHAR(4),
 Ccredit SMALLINt,
 FOREIGN KEY (Cpno) REFERENCES Course(Cno)
 );
