需要INNER加入UPDATE OUTPUT与另一个表返回的结果集并返回结果.可能吗？
这是一个小例子：
CREATE TABLE [dbo].[Customers] ( [CustomerId] [int],[CustomerName] [nvarchar](50) ) GO CREATE TABLE [dbo].[Orders] ( [OrderId] [int],[OrderName] [nvarchar](50) ) GO CREATE TABLE [dbo].[CustomerOrders] ( [CustomerId] [int],[OrderId] [int] ) GO INSERT INTO CustomerOrders (CustomerId,OrderId) VALUES (1,1) INSERT INTO CustomerOrders (CustomerId,2) INSERT INTO CustomerOrders (CustomerId,OrderId) VALUES (2,1) GO
需要更新CustomerOrders表上的OrderId并返回客户的名称,全部为1次.到目前为止,我只能返回CustomerIds：
UPDATE CustomerOrders SET OrderId=NULL OUTPUT Deleted.CustomerId WHERE OrderId='1'
解决方法
Tsql / sql Server 2005支持UPDATE子句中的JOIN – 请参见
documentation：
UPDATE CUSTOMERORDERS SET orderid = NULL OUTPUT c.customername FROM CUSTOMERORDERS co JOIN CUSTOMERS c ON c.customerid = co.customerid
