Run the query in the right panel.
In this step, base tables will be created that will be used in a join.
The Parts table contains some part numbers and a quantity number. For instance, there may be part #1 ("wood" screw) and a total of 10 of these in stock. This table will be used to join with a description table, but using a Fetch first command instead of other SQL techniques.
The Parts Description table contains some information on the part numbers. Note that there are multiple descriptions of some part numbers.
What you should see after running is two result sets underneath the query panel to verify the tables have been created and filled with data correctly.
