如何在SQL Server中使用CTE执行多个查询？

Question

如何使用CTE执行多个查询。

with 
CTE1 as select (...)
,
CTE2 as select (...)

insert into table1 from CTE1
insert into table2 from CTE2

我收到错误Invalid object name CTE2。它看不到我的CTE2。它似乎只执行一个查询。在insert into table1 from CTE1之后，它被编程为工作结束了。如何强制它移动到代码的更多行。

Answer 1

怎么样：

with CTE1 as select (...)
insert into table1 select <cols> from CTE1
GO

with CTE2 as select (...)
insert into table2 select <cols> from CTE2
GO

Answer 2

你不能用CTE做到这一点。

CTE仅在查询范围内可用，您不能使用一个查询来执行两个insert语句。

在你的情况下，我只会这样做：

insert into table1 select ... /* the select you had in CTE1*/
insert into table2 select ... /* the select you had in CTE2*/
