Question
Let us consider the following relational database .
Students(stuID, lastName, firstName, major, gpa)
Faculty(facID, name, deptName, rank)
Classes(classNhmber, facID, schedule, room)
Enrolls(stuID, classNumber, grade)
The primary keys are underlined. The referential integrity constraints are as follows:
The column facID of relation Classes that references table Faculty,
The column of stuID of relation Enrolls that references table Students, and
The column classNumber of relation Enrolls that references table Classes.
The following SQL statement is intended to define the table Students. However, this statement does not work correctly.
CREAT TABLE Students(
lastName VARCHAR(20),
firstName VARCHAR(20),
major VARCHAR(40)
gpa DECIMAL(3,2),
PRIMARY KEY(stuID));
However, this statement does not work correctly. Briefly explain why and list the corrected SQL statement.
