Returns the application name for the current session if set by the application.
The application name is provided by the client and is not verified in any way. Do not use APP_NAME as part of a security check.
Use APP_NAME when you want to perform different actions for different applications. For example, formatting a date differently for different applications, or returning an informational message to certain applications.
To set an application name in Management Studio, in the Connect to Database Engine dialog box, click Options. On the Additional Connection Parameters tab, provide an app attribute in the format ;app='application_name'
The following example checks whether the client application that initiated this process is a SQL Server Management Studio session and provides a date in either US or ANSI format.

The date is ' + CONVERT ( varchar(100) , GETDATE(), 101) + '.'; ELSE PRINT 'This process was started by ' + APP_NAME() + '. The date is ' + CONVERT ( varchar(100) , GETDATE(), 102) + '.'; GO
