Until next version of SQL Server released, you can use following condition

SELECT *
      FROM sys.databases
      WHERE database_id > 4

>I want to select all dbname, but filter System Databases (master,model,msdb,tempdb).
>I see the Microsoft Sql Server Management Studio group master,model,msdb,tempdb to System Databases.
>But i don't know how to filter ? Thank you ~~~
>
>

>
>EXEC sp_databases
>
>select * from   sys.master_files 
>
