Describe

The command USER_NAME in SQL Server returns database username information based on the id passed. If no id is specified, this function returns the name of the current user.

Syntax

To use the command USER_NAME in SQL Server, we use the following syntax:

 USER_NAME([id_number])

Parameters :

  1. id_number: The id number associated with the user in SQL Server.

Note :

  1. If the value is passed to id, USER_NAME returns the username that represents that id.
  2. If the id number is not provided, USER_NAME will return the current username in SQL Server.
  3. See also CURRENT_USER, SYSTEM_USER and SESSION_USER functions.
  4. USER_NAME can be used in later versions of SQL Server: SQL Server 2017, SQL Server 2016, SQL Server 2014, SQL Server 2012, SQL Server 2008 R2, SQL Server 2008, SQL Server 2005.
