Question at position 16 ________ takes a value of TRUE if a subquery returns an intermediate results table which contains one or more rows.ANYHAVING EXISTS IN

Option 1: ANY. While ANY is used in SQL to compare a value with any value in a set or subquery (e.g., x = ANY (subquery)), it does not itself evaluate to TRUE based on whether a subquery returns rows. It’s not the operator that yields a Boolean TRUE for the existence of rows in the subquery’s result, so this is not the correct choice in the given context.

Option 2: HAVING. The HAVING clause is used to filter groups after aggregation, applying a condition to grouped results. It does not represent a Boolean value produced by a subquery's result set. Therefore, HAVING is not the operator described in the prompt.

Option 3: EXISTS. The EXISTS operator returns TRUE if the subquery returns one or more rows, i.e., if the intermediate results table contains at least one row. This aligns exactly with the description in the question, making EXISTS the natural fit for expressing “subquery returns an intermediate results table which contains one or more rows.”

Option 4: IN. The IN operator checks whether a value matches any value in a list or in a subquery’s result set, but it yields TRUE based on a comparison to the subquery’s results rather than simply indicating the existence of rows. It is not the operator described by the prompt, since the question emphasizes the subquery returning rows rather than a membership test against those rows.

Additional nuance: The essence of EXISTS is about the mere presence of rows in the subquery’s output, not about the actual values inside those rows. This makes it the canonical choice for “subquery returns an intermediate results table which contains one or more rows” in many SQL contexts.
