Column name or number of supplied values does not match table definition. Reviewed my code multiple times. What do I do?

Question

I am learning how to use MySQL currently, and as an extra bonus assignment we are creating a database with foreign keys, primary keys, and composite keys. I keep running into the same exact error and it's starting to really get to me, I have no idea how to solve it.

I am making an SQL database and I have created the Query. When I execute it I get the error message:

Column name or number of supplied values does not match table definition.

I am not sure where I am going wrong. I don't think I have any typos, I don't seem to have any stray characters.

What do I do?

EDIT: I fixed the small issues in my code, yet it's still broken.

Answer 1

There are two issues:

• In CREATE TABLE statement for tblGrades , you are missing specifying Char length for CourseCode
• In CREATE TABLE statement for tblStudents , you are missing specifying Char length for MajorCode

Change to following:

CREATE TABLE tblStudents (
        StudentNumber INT,
        StudentFirst CHAR(20),
        StudentLast CHAR(20),
        MajorCode CHAR(3), -- you missed specifying length as 3 here
        PRIMARY KEY (StudentNumber),
        FOREIGN KEY (MajorCode) REFERENCES tblMajors(MajorCode));

CREATE TABLE tblGrades (
        StudentNumber INT,
        CourseCode CHAR(8),  -- you missed specifying length as 8 here
        Grade DECIMAL NOT NULL,
        InstructorNumber INT,
        FOREIGN KEY (StudentNumber) REFERENCES tblStudents(StudentNumber),
        FOREIGN KEY (CourseCode) REFERENCES tblCourses(CourseCode),
        FOREIGN KEY (InstructorNumber) REFERENCES tblInstructors(InstructorNumber),
        PRIMARY KEY (StudentNumber, CourseCode));

Answer 2

First, you need to tell how many decimal places and digits you have on grade. Let's say 2 decimal places.

Grade DECIMAL(3,2) NOT NULL

Then, try inserting this way

INSERT INTO tblGrades
(StudentNumber, CourseCode, Grade, InstructorNumber)
VALUES (200000002, 'COMM2201', 65.00, 99990);
