How To Create a User Name in a Database?

Answer:

User names are security principals at the database level. If you want to allow a login name to access a specific database, you need to create a user name in that database and link it to the login name.

Creating a user name can be done by using the "CREATE USER" statement as shown in this tutorial exercise:

-- Login with "sa"

-- Create a login
CREATE LOGIN ggl_Login WITH PASSWORD = 'IYF'
GO

-- Select a database
USE GlobalGuideLineDatabase;
GO

-- Create a user and link it to a login
CREATE USER ggl_User FOR LOGIN ggl_Login;
GO

Login name "ggl_Login" should be able to access database "GlobalGuideLineDatabase" through user name "ggl_User".
