First (if you haven't already done so) run the script shown above to generate the Doctor Who training database.
Write a query to add Shaun the Sheep as Doctor Who number 13 in the tblDoctor table, but first begin a transaction:
-- this should go within a transaction
INSERT INTO tblDoctor(
) VALUES (
'Shaun the Sheep',
Extend this query (without running it yet) so that it:
Use the SQL syntax IF ... ELSE ....
Finally, display a list of all of the doctors (the rows from the tblDoctor table). Now run your query - it should show the original 12 doctors (Shaun the Sheep has not beeen added).
Amend your query to test whether 2 + 2 = 5, and rerun it. You should now get your new doctor:
The transaction has been committed, and the new doctor appears in the list.
Manually delete this added row, then (optionally) save this query as Baad example.sql and close it down.
