sql - OUTPUT 子句与 scope_Identity()

Question

OUTPUT 子句与 scope_Identity() 有什么区别？优点缺点？

举个例子，

create table myTable 
(   
Id int identity(1,1) primary key clustered,   
myData varchar(50) not null   
);

create table #myTempTable (i int not null);

insert myTable (myData)

output inserted.Id into  #myTempTable

values ('MyData');

select * from #myTempTable
