问题描述

我尝试通过搜索引擎、MSDN 等进行搜索.但什么也做不了.对不起,如果这已经被问过.使用 T-SQLBetween"关键字和使用比较运算符之间有什么性能差异吗?

I've tried searching through search engines,MSDN,etc. but can't anything. Sorry if this has been asked before. Is there any performance difference between using the T-SQL "Between" keyword or using comparison operators?

推荐答案

通过在两种情况下检查查询计划,您可以很容易地检查这一点.我所知道的没有区别.虽然 BETWEEN 和 "<" 之间存在逻辑差异和 ">"... BETWEEN 包含在内.它相当于<="和=>".

You can check this easily enough by checking the query plans in both situations. There is no difference of which I am aware. There is a logical difference though between BETWEEN and "<" and ">"... BETWEEN is inclusive. It's equivalent to "<=" and "=>".
