How we can use CTE in subquery in sql server?
like ..
选择
id
(我想在这里使用CTE),
name
from table_name
select id (i want to use CTE here), name from table_name

仅在顶部定义您的CTE并在子查询中访问它即可?
Just define your CTE on top and access it in the subquery?
WITH YourCTE(blubb) AS
(
SELECT 'Blubb'
)
SELECT id,
(SELECT blubb FROM YourCTE),
name
FROM table_name
