What is user in SQL?

A user is a database level security principal. Logins must be mapped to a database user to connect to a database. A login can be mapped to different databases as different users but can only be mapped as one user in each database. In a partially contained database, a user can be created that does not have a login.

A Login is an identity used to connect to a SQL Server instance. A User allows you to log into a SQL Server database and is mapped to a Login. So you will need to first create a Login, before you can create a User in SQL Server.

After creating a user with “SQL User without Login” type, the user will have to login using their own credentials into SQL Server. It means that the user who is logged in will have his/her own username and password. Once the login is done in SQL Server, the user will be able to use the application.
