SQL has a JOIN ON syntax that can be used to create inner joins and outer joins.

  • A.True
  • B.False

Answer: A

Correct answer: True

The JOIN ... ON syntax expresses the join condition explicitly and supports INNER, LEFT, RIGHT and FULL OUTER forms. It is preferred to putting the condition in the WHERE clause because the join and the filtering are then visibly separate, and because an outer join cannot be written the older way at all.
