Execute a stored procedure as another user permiss

Question

I faced the following problem: there's a user who has to execute a stored procedure (spTest). In spTest's body sp_trace_generateevent is called. sp_trace_generateevent requires alter trace permissions, and I don't want user to have it. So I would like user to be able to execute spTest. How can I do that?

Answer 1

This is what I did (and succeeded):

let Source = Sql.Database("server", "database", 
    [Query= "EXECUTE AS USER='user' EXECUTE [schema].[spname] 'parm1', 'parm2'"])

Answer 2

As others have suggested you can achieve what you wish using the Execute As clause. For examples of implementation choices take a look at the Books Online documentation for the Execute As clause.

For further reading and to develop more understanding of this topic, what you are looking to achieve comes under the security concept of Context Switching.

Answer 3

Try this:

EXECUTE AS user = 'special_user'

Answer 4

When you go to execute that specific stored procedure you will need to create a different connection using the needed user credentials.
