SQL中With关键字的简单用法

select * from dbo.HRReOrPuType

/* with 的写法避免了产生临时表的IO，更多建议请参考：http://wudataoge.blog.163.com/blog/static/80073886200961652022389/ */
with t_rePuType1 as
(
select Id from HRReOrPuType where typeName like '出勤奖%'
)/* 后面可以接N个，但with结束后，必须使用with定义的这些变量 ,
t_rePuType2 as
(

) */
select * from dbo.HRUserReAndPu where hRReOrPuTypeId in (select * from t_rePuType1)
