Find User in SQL Server

Do any queries on SQL Server return all User created?

On SQL Server there is a system table called sys.database_principals. You can run the above query and the result is all Users created on the database and information about them.

To retrieve all Users in SQL Server, run the following command:

 SELECT * 
 FROM master.sys.database_principals;

System sys.database_principals includes the following columns:

COLLECTION NOTE User name created in the CREATE USER principal_id command principal code (numeric value) type

Type principal:

S = User of SQL Server
U = User of Windows
G = Windows group
A = Application role
R = Database role
C = Certificate has mapped
K = Asymmetric key is mapped

For older versions

In older versions of SQL Server, you can retrieve all Users by using the sys.sysusers table in SQL Server 2000. The command is as follows:

 SELECT *
