I have seen various methods used when retrieving the value of a primary key identity field after insert.
declare @t table (
id int identity primary key,
somecol datetime default getdate()
)
insert into @t
default values
select SCOPE_IDENTITY() --returns 1
select @@IDENTITY --returns 1
Returning a table of identities following insert:
Create Table #Testing (
id int identity,
somedate datetime default getdate()
)
insert into #Testing
output inserted.*
default values
What method is proper or better? Is the OUTPUT method scope-safe?
