Question

I’m using this code to create a new user.

/****** Object:  User [primebox] ******/
IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'primebox')
CREATE USER [primebox] FOR LOGIN [primebox] WITH DEFAULT_SCHEMA=[primebox]
GO

and I got the following error when I try to create this specific user.

Msg 15007, Level 16, State 1, Line 1
‘primebox’ is not a valid login or you do not have permission.

The part that I don’t understand is, I can create others users but this one in particular looks invalid

I tried to rename my database and got this error

Unable to rename primeboxs. (ObjectExplorer)

Rename failed for Database ‘primebox’. (Microsoft.SqlServer.Smo)

An exception occurred while executing a Transact-SQL statement or
batch. (Microsoft.SqlServer.ConnectionInfo)

The database could not be exclusively locked to perform the operation.
(Microsoft SQL Server, Error: 5030)

My guess is that the problem is the database name… but I got the code from another database (I’m creating a ‘wanna be’ backup) with the same user and database names. So I’m in a corner here… Any help will be a LOT appreciated =)

In SQL Server, users are different to logins.

To create a user for a database, you first have to create a login for the server using the create login syntax
