我是靠谱客的博主开放外套，最近开发中收集的这篇文章主要介绍存储里判断大小，然后赋值，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

存储问题：

case q9 when 0 then '+''''+'新單'+''''+' when 1 then '+''''+'再協商'+''''+' end as jb

假如我要换成　q9<=100 && q9>=85　的判断怎么改？

方法一：

set @strSql = 'select case when (q9<=100 and q9>=85) then '+''''+'A'+''''+' when (q9<=84 and q9>=70) then '+''''+'B'+''''+' when (q9<=69 and q9>=55) then '+''''+'C' +''''+' when (q9<=54 and q9>=40) then '+''''+'D'+''''+' when (q9<40) then '+''''+'E'+''''+' end as jb,* from jdkh'

方法二：

case when q9 between 85 and 100 then '+''''+'新單'+''''+' when 1 then '+''''+'再協商'+''''+' end as jb

-------------------------

case when用法和and 后加条件
SELECT A.OrderSID as InvId,
       E.BizInvType as TypeCode,
       E.TypeName as TypeName,
       B.SimpleName as CorpName,
       C.StorName as StorName,
