I am working with a basic table design for a MySQL database. This database project was given as an idea, mainly aimed for an educational purpose. There are a total of 11 tables which 2 are used for bridging purposes. I tried to properly set primary and foreign keys. I am not sure how to write the query that will create the 11 tables and bridge them all at once. HERE I have attached a visual diagram of these tables.
Through basic learning I can create one table but not sure how to advance from here:
CREATE TABLE Course ( Course_ID INT, Course_Abbreviation VARCHAR(5), Course_Number INT, Section_Number INT, Professor_ID INT, Status VARCHAR(10) ) TYPE=innodb;
You’re almost there, you have to define PRIMARY and FOREIGN keys for the attributes within the tables, an example with the Students, Course, and Course_Br_Students table is:
CREATE TABLE Students( PRIMARY KEY Student_ID SERIAL INTEGER, Username VARCHAR(255), First_name VARCHAR(255), Email VARCHAR(255), Phone number INTEGER, Beginning_Date TIME, Ending_Date TIME, Max_hours INTEGER, ) CREATE TABLE Student_Br_Course( FOREIGN KEY Student_ID REFERENCES Students(Student_ID), FOREIGN KEY Course_ID REFERENCES Courses(Course_ID), Role VARCHAR(255), Status BOOLEAN, ) CREATE TABLE Courses( PRIMARY KEY Course_ID INTEGER, Course_Abbreviation VARCHAR(255), Course_Number INTEGER, Section_number INTEGER, Professor_ID INTEGER, )
Here’s a reference for understanding how to create tables with PRIMARY and FOREIGN keys:
