                  问题描述

                  CTETemporary Tables 哪个更高效?

                  推荐答案

                  我会说它们是不同的概念,但与粉笔和奶酪"没有太大区别.

                  I'd say they are different concepts but not too different to say "chalk and cheese".

                  • 临时表适合重复使用或对一组数据执行多次处理.

                  • A temp table is good for re-use or to perform multiple processing passes on a set of data.

                  CTE 可用于递归或简单地提高可读性.
                  并且,像视图或内联表值函数一样,也可以像宏一样在主查询中展开

                  A CTE can be used either to recurse or to simply improved readability.
                  And, like a view or inline table valued function can also be treated like a macro to be expanded in the main query

                  临时表是另一个在范围方面有一些规则的表

                  A temp table is another table with some rules around scope

                  我已经存储了我同时使用的过程(和表变量)

                  I have stored procs where I use both (and table variables too)

                  这篇关于哪个性能更好,CTE 或临时表?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
