Question

Group functions can only be nested to a depth of two.​

Quizplus · Accepted Answer

Group functions can only be nested to a depth of two because SQL Server has a limitation that prevents nesting group functions more than two levels deep. This limitation is in place to prevent performance issues and ensure that queries can be executed efficiently.
