无法弄清楚如何使用多个 CTE
这失败了
; with [cteOne] as (
select 1 as col
),
[cteTwo] as (
select 2 as col
)
select 'yesA' where exists (select * from [cteOne])
select 'yexB' where exists (select * from [cteTwo])
这可行 - 但这不是我需要的
; with [cteOne] as (
select 1 as col
),
[cteTwo] as (
select 2 as col
)
select * from [cteOne]
union
select * from [cteTwo]
真正的语法是连接到 row_number() 分区
我刚刚结束使用派生表
第一个失败，因为一个 CTE 或一组 CTE 后面只能跟一个语句。
你可以将其重写为
; with [cteOne] as (
select 1 as col
)
select 'yesA' where exists (select * from [cteOne])
; with [cteTwo] as (
select 2 as col
)
select 'yexB' where exists (select * from [cteTwo])
