Question

我正在进行插入和更新2表。当我插入时，我希望新创建的Id更新新表。

insert into Event(EventName, EventManager, EventManagerShortName, EventTicketId) Values(@eventname, (select ManagerShortName From Manager where ManagerID = @managerid), @eventticketid)

我可以这样做：

set @eventId = select Eventid from Event where EventTicketId = @eventticketid

update ScheduledEvents set EventID = @eventid, IsPaymentCompleted = true,  IsCancelled = false where ScheduledDate = @scheduleddate

有没有更好的方法来执行此操作，然后每次使用变量来获取新创建的ID？

使用SCOPE_IDENTITY()：http://msdn.microsoft.com/en-us/library/ms190315.aspx

此函数返回当前会话中最后创建的标识值。

insert into Event
(EventName, EventManager, EventManagerShortName, EventTicketId)
Values
(@eventname, (select top 1 ManagerShortName From Manager where ManagerID = @managerid), @eventticketid)


set @eventId = scope_identity() --must immediately follow the above line

update ScheduledEvents 
set EventID = @eventid
, IsPaymentCompleted = true
,  IsCancelled = false 
where ScheduledDate = @scheduleddate
