SQL Schema
Exercise 1 – Translating ERD to SQL Schema.
Create a new database called STUDENT2 and using the SQL
code from student1 write the SQL code (schema) to create a
STUDENT2 database based on the STUDENT2 ERD provided
below.
a.
Generate the tables for the above students2 erd and choose suitable
data types, widths and constraints, including NULL/NOT NULL.
b.
In Query Analyser create, save and run a script file/files using SQL
statements to create the tables with appropriate primary key and foreign key
constraints.
c.
Check the structure of the tables. If any of the structures are incorrect,
either delete the table using the DROP command and create it again or use
the ALTER command to change the structure.
NB: If a table is referenced by a foreign key constraint, you will need to break the
relationship (the joining lines) before you can drop the table.

CONSTRAINTS
Exercise 2 – Checking the Primary and Foreign Key
Constraints
You should have the following primary and foreign key constraints. If you
don’t, alter the table structures accordingly.
a. Module: a primary key constraint on Moduleno.
b. StudentModule: a composite primary key constraint on Studentno and
Moduleno, a foreign key constraint on Studentno and a foreign key constraint
on Moduleno.
c. CourseModule: a composite primary key constraint on Courseno and
Moduleno, a foreign key constraint on Courseno and a foreign key constraint on
Moduleno.
Exercise 3 – Unique Constraints
Create and run a script file/files to:
a. Alter the Tutor table, adding a UNIQUE constraint on Email. What will this
do?
b. Alter the Student table, adding a UNIQUE constraint on Email.
c. Alter the Tutor table again, adding a CHECK constraint to ensure that only
the following job titles are permitted: Lecturer, Senior Lecturer, Principal
Lecturer and Reader. (Hint: use IN).
d. Look at all the table structures and contents. Are there any other constraints
you could sensibly add? If so, do so.
e. Use the system stored procedure sp_help to view all your constraint
definitions and names.
INSERT
Exercise 4 – Inserting Rows of Data
Create and run a script file/files to:
1. Insert the rows of data into the tables

2. Check the rows of data in the tables. If the data are incorrect, use the
UPDATE statement to make the necessary changes. Use SQL Server’s Help
facility if you’re not sure of the syntax of the UPDATE statement.
