SQL - 获取子查询中表的引用

Question

是否可以从子查询访问表？

Select d.table_c.*
from (with table_c as (select *
                       from table_a)
      select *
      from table_b
      where table_a.id = table_b.id) as d

table_c在d的子查询中，我试图使用d.table_c访问它，但它似乎不起作用。

Answer 1

您不能将CTE用作子查询。但你可以写下面的内容。

;WITH table_c
as
(SELECT * FROM table_a)
SELECT *
from table_b b
INNER JOIN table_c c on c.id = b.id
