A complex query consists of eight populated tables that are all connected via INNER JOIN operands as shown:

You modify the query and replace the SELECT operand with SELECT STRAIGHT JOIN.

What is the effect of adding STRAIGHT JOINs to the query?

  • A

    The optimizer processes only the JOINs in the sequence listed in the query.

  • B

    The optimizer will only JOIN the tables by using their PRIMARY KEYS or UNIQUE constraints.

  • C

    The optimizer will only JOIN the tables in sequence from smallest to largest.

  • D

    The optimizer ignores all terms in the WHERE clause until all JOINs have been completed.
