====== SQL Server - "Managing database users and logins" ======

In Microsoft SQL Server there are two forms of "User ID's":
  - There is a SQL Server "Login" which aloows the user to connect to the SQL Server.  This data is usually found under the "Security" folder.
  - Under the Databases --> <DBNAME> --> Security --> Users folder are the users that are allowed to access the database in question.


**Question**\\
What happens when you are restoring a foreign database into your SQL Server.  The Database has a set of users allowed to access it but there is no corresponding SQL Server "Login"?

**Answer**\\
This is where **sp_change_users_login** comes into play.  There are two main ways to use the stored procedure:
\\
    * The following code block shows you how to automatically create a "Login" for the "User" in your recently restored database.
<code>
use <DBNAME>
go
exec sp_change_users_login 'Auto_Fix', '<USER>',NULL,'<PASSWORD>'
go
</code>
  * The following code block associates the "User" in the database to an existing "Login".
<code>
use <DBNAME>
go
exec sp_change_users_login 'Update_one', '<USER>','<LOGIN>'
go
</code>
