Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

If you haven't already done so, run the stored procedure in the above folder to generate a database of books and authors.

Create a query or stored procedure to create the following table of book genres called tblGenre (the rating is a number between 1 and 10 you can assign to each genre):

SQL exercise - Creating tables (image 1)

The table should have 3 columns - you get bonus points for indexing the GenreName column

Now add code to insert records into this table then display them - here's a suggestion for what to add:

If you don't like science fiction, your ratings will be different

Run your query to check it works - you should see something like this:

SQL exercise - Creating tables (image 3)

Here we've also used @@IDENTITY to show the id number of the last row added

Now run your query again - it should now fall over, because the tblGenre table already exists.

Add a statement at the start of your query to drop the tblGenre table if it exists, and run the query again - it should now work.

Optionally, save your query as Generate genres.sql, then close it down.
