以下是我当前用于删除甚至更新的内容：

DELETE           w
FROM             WorkRecord2   w,
                 Employee      e
WHERE            w.EmployeeRun = e.EmployeeNo
             AND w.Company = '1' 
             AND w.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。

在SQL Server Management Studio中，我可以轻松创建SELECT查询：

SELECT Contact.Naam_Contactpersoon, Bedrijf.BedrijfsNaam, Bedrijf.Adres, Bedrijf.Postcode
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf

我可以执行它，我的所有联系人都会显示出来。

现在将SELECT更改为DELETE：

DELETE Contact
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf

您在SELECT语句中看到的所有记录都将被删除。

您甚至可以使用相同的过程创建更困难的内部联接，例如：

DELETE FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf
INNER JOIN LoginBedrijf ON Bedrijf.IDLoginBedrijf = LoginBedrijf.IDLoginBedrijf

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'
