SQL with as

with temp as(

select *From tb_order where Auditing=2 and AuditingTime>='2013-04-01' and Flag=2
)
select *from temp where EbayAccountID=21

　　

相当于临时表 temp 分析器可以智能提示 临时表却不能。

 临时表

select * into #temp From tb_order where Auditing=2 and AuditingTime>='2013-04-01' and Flag=2

select * From #temp where EbayAccountID=21

　　

declare @flag int=2;
with temp as(

select *From tb_order where Auditing=2 and AuditingTime>='2013-04-01' and Flag=@flag
)
select *from temp where EbayAccountID=21

　　

declare @flag int=2; 这里的分号不可少 否则会报错
关键字 'with' 附近有语法错误。如果此语句是公用表表达式、xmlnamespaces 子句或者更改跟踪上下文子句，那么前一个语句必须以分号结尾。
