Integration with Modern SQL Features Cross apply integrates seamlessly with other advanced SQL features, such as the OFFSET FETCH clause for pagination. Second, prefer inline table-valued functions over multi-statement versions, as the former are generally treated as black boxes that the optimizer can inline and optimize more aggressively.

Outer apply, however, functions like a left join, preserving the left-side rows and filling the right-side columns with nulls. This avoids the need for temporary tables and keeps the logic inline with the primary query, resulting in cleaner execution plans and improved readability.
This behavior is crucial when the logic on the right depends on the specific values of the current row being processed. Using cross apply with a user-defined or built-in string splitter allows a query to break these values into separate rows.
