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 training courses and delegates.

We want to create a query which shows all companies which either are in the retail sector or which have more than 12 people working there.  To do this, first select all of the companies in the retail sector (there are only 2) into a new temporary table called #Org:

SQL exercise - Temporary tables and table variables (image 1)

This is what you should have so far

Now add code to insert all companies employing more than 12 people into the same table (you could use a subquery to do this, as shown below):

An example of code to pick out these organisastions

Select all of the records from the temporary table that you've compiled.  The final answer should look like this:

Primark and Kingfisher PLC qualify as being part of the retail sector

Optionally, save this query as Retail or big orgs.sql, then close it down.
