Is there a way to change an owner inside the context of a sproc?

Like in DB2 you can Bind code to a particular owner, such that one code would execute against dbo, and another to HR (or whatever)

I've never heard or seen of this before in sql server

Anything like that conceptualy in SQL?

EDIT:
lost part of my post...

I don't know of a way to "bind" a block of code to a specific user but you could create 2 versions of the SP, one owned by dbo, the other owned by HR.

exec myProc (as HR)
exec myProc (as dbo)

Of course you could also create an IF block with the <condition> being a test for user_name() or system_user

yeah, that's what I thought

I say it's a design issue

This what you want to do? The stored proc uses EXECUTE AS to set the user context dynamically.


create proc dbo.xx (@user sysname =null)
with execute as 'dbo'
as
if @user is not null begin execute as user = @user end
select [Current user] = user_name()
go
exec dbo.xx
go
exec dbo.xx 'dummy'
go
drop proc dbo.xx


Results:
Current user
------------------------ 
dbo

(1 row(s) affected)

Current user
------------------------ 
Dummy

(1 row(s) affected)
