I think it’d be easier to remember all these clauses if they were introduced in the following order:

  1. SELECT

We need to know how to view the data after adding, modifying, deleting rows and columns, to check whether we have done it correctly. So SELECT is the first thing to learn.

  1. CREATE (and discuss constraints)

The topic on constraints is a bit advanced, but it should come right after we learn CREATE.

  1. INSERT
  2. UPDATE
  3. DELETE

These three clauses all deal with rows. They should be taught together.

  1. ALTER TABLE

This one deals with columns, and in this sense is different from the above three on rows.
