使用 WITH 查询执行 INSERT INTO

Question

我在这个 SO 解决方案 here 中找到了一个查询，并想在我正在处理的一个查询中使用它。解决方案中的示例查询如下：

;with t1 as (
    select col1, row_number() over (order by col1) rn
    from table1 
),
t2 as (
    select col2, row_number() over (order by col2) rn
    from table2
)
select col1,col2
from t1 full outer join t2 on t1.rn = t2.rn

而不是运行这个查询多次（因为我需要在多个地方使用上述查询的结果）我想做如下的事情：

declare @tempTbl table (col1 int, col2 int)

insert into @tempTbl (col1, col2)
;with t1 as (
    select col1, row_number() over (order by col1) rn
    from table1 
),
t2 as (
    select col2, row_number() over (order by col2) rn
    from table2
)
select col1,col2
from t1 full outer join t2 on t1.rn = t2.rn

但是那个 ;with 引起了麻烦...求助...

常见的 table 表达式在之前插入：

; with  t1 as 
        (
        ...
        )
,       t2 as 
        (
        ...
        )
insert  @tempTbl
        (col1, col2)
select  col1
,       col2
from    t1
full join
        t2
on      t1.rn = t2.rn
;

使用 WITH 查询执行 INSERT INTO

Perform INSERT INTO with WITH query
