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)

您没有指定“公司”和“日期”的表，您可能想解决这个问题。

使用MERGE的标准SQL：

MERGE WorkRecord2 T
   USING Employee S
      ON T.EmployeeRun = S.EmployeeNo
         AND Company = '1'
         AND Date = '2013-05-06'
WHEN MATCHED THEN DELETE;

Devart给出的答案也是标准SQL，尽管不完整。它应该更像这样：

DELETE
  FROM WorkRecord2
  WHERE EXISTS ( SELECT *
                   FROM Employee S
                  WHERE S.EmployeeNo = WorkRecord2.EmployeeRun
                        AND Company = '1'
                        AND Date = '2013-05-06' );

关于上述内容，需要注意的重要一点是，很明显，删除的目标是单个表，正如第二个示例中通过要求标量子查询而强制执行的那样。

对我来说，各种专有语法答案更难阅读和理解。我想frans eilling的回答中最好地描述了的心态，即编写代码的人不一定关心将阅读和维护代码的人。

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'

只需在DELETE和FROM之间添加要删除记录的表的名称，因为我们必须指定要删除的表。还要删除ORDERBY子句，因为删除记录时没有要排序的内容。

因此，您的最终查询应该如下所示：

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

这可能对你有帮助-

DELETE FROM dbo.WorkRecord2
WHERE EmployeeRun IN (
    SELECT e.EmployeeNo
    FROM dbo.Employee e
    WHERE ...
)

或者试试这个-

DELETE FROM dbo.WorkRecord2
WHERE EXISTS(
    SELECT 1
    FROM dbo.Employee e
    WHERE EmployeeRun = e.EmployeeNo
        AND ....
)

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。
