Not sure if this will omit the Report server databases since I am not running one  but from what I have seen  I can omit system user owned databases with this SQL       SELECT  db  name  as dbname      FROM  master   sys   databases  db     LEFT OUTER JOIN   master   sys   sysusers  su on su sid   db owner sid     WHERE su sid is null     order by db  name

If you want to omit system databases and ReportServer tables  if installed  select DATABASE NAME   db name s mf database id  from sys master files s mf where     s mf state   0 -- ONLINE     and has dbaccess db name s mf database id     1     and db name s mf database id  NOT IN   master    tempdb    model    msdb       and db name s mf database id  not like  ReportServer   group by s mf database id order by 1   This works on SQL Server 2008 2012 2014  Most of query comes from  quot sp databases quot  system stored procedure  I only removed unneeded column and added where conditions

Execute    SELECT name FROM master sys databases   This the preferred approach now  rather than dbo sysdatabases  which has been deprecated for some time     Execute this query   SELECT name FROM master dbo sysdatabases   or if you prefer  EXEC sp databases

in light of the ambiguity as to the number of non-user databases  you should probably add   WHERE name NOT IN   master    tempdb    model    msdb      and add the names of the reporting services databases

Don t Get confused  Use the below simple query to get all the databases   select   from sys databases   If u need only the User defined databases   select   from sys databases WHERE name NOT IN   master    tempdb    model    msdb       Some of the System database names are  resource distribution reportservice reportservicetempdb  just insert it into the query   If u have the above db s in your machine as default
