Question

Is there a SQL Server command to connect a user of a single database to a login for the database server of the same name?

For example:

Database Server – Default Instance
Database: TestDB

Server Login – TestUser
Existing user on TestDB – TestUser

If I try to make the TestUser login a user of the TestDB database, the “User, group, or role” already exists.

Does anybody know of an easy way to assign the DB user to the server login?

Answer 1

The new way (SQL 2008 onwards) is to use ALTER USER

ALTER USER OrphanUser WITH LOGIN = correctedLoginName;
