Q4. Use MySQL or SQL server and Create your database (ensure you save your
CREATE TABLE statement). Highlight any additional constraints added. Ensure AT
LEAST ONE table has a COMPOSITE PRIMARY KEY. The primary and foreign keys
should be added at the same time as your CREATE TABLE statement, i.e., do not
use ALTER TABLE to add them after. (P2,M2,D2)
0 marks if you use any other DBMS or auto generated DDL code.
Q5. Populate all the tables with data (having 8 or more rows per table). Show all
rows, (use SELECT * from <tablename>;) of data in every table created.
Good/suitable TEST DATA created. Note, the tables at the many end of a
relationship should contain more data. (P3,M3,D3)
SQL & QUERIES:
Devise 6 SQL queries that demonstrate appropriate use of the following:
Q6. Use of the BETWEEN logical operator;
Q7. AN example of DISTINCT within your query
Q8. TO_CHAR function;
Q9. An aggregate function in the SELECT list
Q10. A GROUP BY command
Q11. A SUBQUERY;
At least one of the above queries should include data from more than one table
and a different query should demonstrate the use of an OUTER JOIN. (P3,M3,D3)
Include the following for each query:
- Short sentence saying what the query is doing
- SQL Query
- Result
Q12. Devise a DELETE command that tests the foreign keys (testing of the

message means.
Q14. Use an INSERT command to test the primary key (test the entity integrity),
explain what the error message means.
(Include the query and comment on any results. Show at least 2 queries for each
part (l-n): one that work successfully and one that does not.) (P3,M3,D3)
The report should be put together professionally, that is, include a contents page,
each section correctly labelled. Ensure all the diagrams and results are presentable
and in a readable format. If you cannot read it, neither can the lecturer marking
