你的附加分数很准确，所以改为+1:）-Gareth谢谢你的帮助和解释。我不熟悉SQL函数，这当然有帮助！没问题。需要记住的一点是，正如在另一条评论中提到的，您最初使用的内联表值函数（TVF）将比多语句TVF（如公认的答案中所示）性能更好。这是因为内联TVF的行为更像一个视图，因为无论何时调用它，它的定义都会扩展到外部查询中，因此可以对其进行优化，虽然执行了多语句TVF，但从性能角度来看，如果它是内联表值函数而不是多语句表值函数，则效果会更好。只要在开始时将其改为case表达式而不是IF，就可以极大地提高性能。从性能角度来看，如果它是内联表值函数而不是多语句表值函数，则性能会更好。只要在开始时将其改为case表达式而不是IF，就可以极大地提高性能。
