sql - 需要随机化用户表中的名称

Question

我有以下查询，它允许我按行号连接两个表，我正在尝试修改它，以便它使用随机名称表中的随机名称更新订阅者表。

select fo.*, so.*
from (select *, 
              row_number() over (order by FirstName) as rn
      from randomnames
) fo
join (select *,
             row_number() over (order by ID) as rn
       from subscribers) so on fo.rn = so.rn

我将其更新为以下内容以使其正常工作

update subscribers set 
FirstName = fo.Firstname,
LastName = fo.LastName
from
 (select *, 
              row_number() over (order by firstname) as rn
      from _randomnames
) fo
join (select *,
             row_number() over (order by ID desc) as rn
       from subscribers) so on fo.rn = so.rn

       where so.ID = subscribers.ID

Answer 1

尝试以下查询：

;WITH CTE AS
(
    SELECT *, ROW_NUMBER() OVER (ORDER BY ID) AS rn
    FROM subscribers
)
UPDATE so
SET so.[Name] = fo.[Name]
FROM CTE so
INNER JOIN (SELECT *, ROW_NUMBER() OVER (ORDER BY FirstName) AS rn
            FROM randomnames) fo
ON fo.rn = so.rn
