Question

我有CTE并查询此内容

;With CTE_Table as (SELECT ...)
Select * from CTE_Table

现在我尝试将此结果保存到table variable或temporary table。如果我试试

Declare @Table table
(...)
INSERT INTO @Table (...)
HER I PUT THE CODE ABOVE

我在incorrect syntax error声明周围得到WITH。我想Insert Into命令需要Select statement而不是;WITH，而Create Table则相同。我一直在寻找解决方案，但所有I found都不涉及Select Statement之后的;With。如何将上面显示的输出变为temporary table或table variable？

我使用的是SQL Server 2014。

Answer 1

在CTE声明之后立即将insert语句添加到主查询。

declare @T table(ID int);

with C(ID) as
(
  select 1 union all
  select 2
)
insert into @T(ID)
select ID
from C;

select ID
from @T;

Answer 2

DECLARE @t table(
Name nvarchar(MAX),
Id bigint
)

;WITH CTE as (
    SELECT 'Name' as Name , 1 as Id
)
INSERT INTO @t(Name,Id)
SELECT Name,Id FROM CTE


SELECT * FROM @t

如何将查询的CTE输出保存到临时表或表变量中
