Use database inside a stored procedure

Question

I need to make a stored procedure which creates a user in more than one database. Something like this:

USE [database1]

CREATE USER [userLogin] FOR LOGIN [us         


        

Answer 1

SQL Server gives us a system stored procedure to do this. My understanding is that the recommended method would be to use sys.sp_grantdbaccess:

CREATE PROCEDURE usp_CreateTwoUSers

AS
BEGIN

    -- Create a user for a login in the current DB:
    Exec sp_grantdbaccess [userLogin], [name_in_db];

    -- Create a user for a login in an external DB:
    Exec ExternalDatabaseName.sys.sp_grantdbaccess [userLogin], [name_in_db];

END
