另一种方法是使用CTE：

;WITH cte
     AS (SELECT *
         FROM   workrecord2 w
         WHERE  EXISTS (SELECT 1
                        FROM   employee e
                        WHERE  employeerun = employeeno
                               AND company = '1'
                               AND date = '2013-05-06'))
DELETE FROM cte

注意：当您想要删除时，我们不能在CTE中使用JOIN。

这是一次从两个表中删除记录的简单查询。

DELETE table1.* ,
       table2.* 
FROM table1 
INNER JOIN table2 ON table1.id= table2.id where table1.id ='given_id'

您需要指定要从中删除的表。以下是具有别名的版本：

DELETE w
FROM WorkRecord2 w
INNER JOIN Employee e
  ON EmployeeRun=EmployeeNo
WHERE Company = '1' AND Date = '2013-05-06'

这是我的SQL Server版本

DECLARE @ProfileId table(Id bigint)

DELETE FROM AspNetUsers
OUTPUT deleted.ProfileId INTO @ProfileId
WHERE Email = @email

DELETE FROM UserProfiles    
WHERE Id = (Select Id FROM @ProfileId)

您甚至可以执行子查询。喜欢下面的代码：

DELETE FROM users WHERE id IN(
    SELECT user_id FROM Employee WHERE Company = '1' AND Date = '2013-05-06'
)

另一种方法是使用CTE：

;WITH cte
     AS (SELECT *
         FROM   workrecord2 w
         WHERE  EXISTS (SELECT 1
                        FROM   employee e
                        WHERE  employeerun = employeeno
                               AND company = '1'
                               AND date = '2013-05-06'))
DELETE FROM cte
