Can someone please tell me how I can create a user with a password and grant it owner permission to a database that I created in LocalDB in Visual Studio.
It creates a user with no login but I need to create one with a password and owner rights to a database.
- Open SQL Server Object Explorer (e.g. from the Visual Studio View menu)
- Expand your localdb instance in the tree (e.g. (localdb)\MSSQLLocalDB)
- Right click your database and select New Query...
- Execute the following sql:
...
CREATE LOGIN [SomeUser] WITH PASSWORD = 'topsecret';
CREATE USER [SomeUser] FOR LOGIN [SomeUser];
exec sp_addrolemember 'db_owner', 'SomeUser'
