The students table

Let us take a look at the following fields in the table and what work they perform:

Now let us convert this table structure into executable SQL, to create our table, we will be using the CREATE DDL command, followed by TABLE and then append it with the table structure. In SQL, the column description is done by mentioning the column name first and then adding the datatype of the column. The STUDENTS table has multiple columns, and the column information has to be separated by a comma (,).

Now that the query has been executed, the students table has been created. To verify if the students table has been successfully built, and to view a list of existing tables that are in the current database, we can use the SHOW utility command and append that with TABLES:

We have successfully used the show tables; command SQL statement to retrieve a list of existing tables, and have verified that our students table exists in our course_registry database. Now, let us verify if our students table has the same table structure as we originally intended it to have. We will use the DESCRIBE utility command followed by the table name to understand the table structure:

Now let us move on to the courses table, this table will house all the available courses for which a student can register. The courses table will contain a unique identifier for the course (course_id), the name of the course (course_name), and a brief description of the course (course_description).
