These are the steps for a correlated subquery, listed in random order:
1. The WHEREclause of the outer query is evaluated.
2. A candidate row is fetched from the table specified in the outer query.
3. This is repeated for the subsequent rows of the table, until all the rows are processed.
4. Rows are returned by the inner query, after being evaluated with the value from the candidate row in the outer query.
Which is the correct sequence in which the Oracle server evaluates a correlated subquery?
