We start by restating the question in practical terms: Which operator cannot be used with a multiple-row subquery?
Option 1: ANY. The ANY operator compares a value to any one of a set of values returned by the subquery. This is valid when the subquery returns multiple rows, as it effectively checks the condition against at least one of the subquery results. For example, x > ANY (select a from t) is a standard usage.
Option 2: BETWEEN. The BETWEEN operator is used to check if a value lies within a contiguous range defined by two values (low and high). When the subquery returns multiple rows, BETWEEN does not have a defined, single pair of bounds to compare against; it expects scalar endpoints, not a set of values from a multi-row subquery. Therefore, using BETWEEN with a multi-row subquery is not supported and will typically result in an error or unintended behavior.
Option 3: NOT EXISTS. NOT EXISTS is a common pattern that checks whether a subquery returns any rows at all. If the subquery returns no rows, EXISTS (or NOT EXISTS) yields true, and this works perfectly with multiple-row subqueries. It is a standard correlated or uncorrelated subquery usage.
Option 4: NOT IN. NOT IN is used to verify that a value does not match any of the values produced by a subquery. When the subquery returns multiple rows, NOT IN can behave unexpectedly if the subquery returns NULLs, but the syntax and general usage are valid in many SQL dialects. Caution is needed about NULL handling, but it is still a valid construct with multi-row subqueries.
Putting it together, the invalid pairing among the options is BETWEEN, because BETWEEN is designed for comparing a value against a single low and a single high bound, not against a set of rows produced by a multi-row subquery. The other operators (ANY, NOT EXISTS, NOT IN) have established patterns for using with multi-row results, though each comes with its own caveats (such as NULL handling for NOT IN and performance considerations for ALL/ANY).
In summary, BETWEEN cannot be used with a multiple-row subquery due to its requirement for scalar boundary values rather than a set of results.
