As its name implies, a user without login cannot log into SQL Server. However, the “user” exists as a database object and may therefore be granted or denied permissions as may any other user. These permissions, of course, will be exactly those required by your stored procedure code. 26 февр. 2019 г.

What is the difference between login and user in SQL?

SQL Login is for Authentication and SQL Server User is for Authorization. Authentication can decide if we have permissions to access the server or not and Authorization decides what are different operations we can do in a database.

The default system administrator account ("sa") is the first account that hackers will attempt to use to gain access to your data. If running SixBit on a standalone computer, or from the server where SQL Server is installed, Windows Authentication should be used to access that database.
