Let us consider the following relational database. Students(stuID, lastName, firstName, major, gpa) Faculty(facID, name, deptName, rank) Classes(classNumber, facID, schedule, room) Enrolls(stuID, classNumber, grade) The column facID of relation Classes that references the table Faculty, The column StuID of relation Enrolls that references table Students, and The column classNunber of relation Enrolls that references table Classes. The following SQL statement is intended to add a record to the table Students. Assume that the entered value for each column is appropriate. In other words, there is no domain constraint violation. INSERT INTO Students(stuID, lastName, firstName, major) VALUES('950555111', 'Anna' 'Smith', 'BSIT'); However, this statement does not work correctly. Briefly explain why and list the correct SQL statement.
