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.

The aim of this exercise is to display all of the actors who have appeared in films directed by Spielberg, but we'll do it in two passes, using a CTE:

SQL exercise - Derived tables and CTEs (image 1)

The first few rows of the 24 actors we should see at the end

Yes, you could do this all with a single SELECT statement, but using the CTE - arguably - makes the whole thing easier to understand.

To accomplish this:

  • create a CTE which shows all of the films directed by Spielberg; then
  • link the results of this CTE to the tblCast and tblActor tables to show the results above

When you've finished, save this query as Spielberg, then close it down.
