How should I run this query against all the DB?
SELECT db_name(), dbschemas.[name] as 'Schema',
dbtables.[name] as 'Table',
dbindexes.[name] as 'Index',
indexstats.avg_fragmentation_in_percent,
indexstats.page_count
FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS indexstats
INNER JOIN sys.tables dbtables on dbtables.[object_id] = indexstats.[object_id]
INNER JOIN sys.schemas dbschemas on dbtables.[schema_id] = dbschemas.[schema_id]
INNER JOIN sys.indexes AS dbindexes ON dbindexes.[object_id] = indexstats.[object_id]
AND indexstats.index_id = dbindexes.index_id
WHERE indexstats.database_id = DB_ID()
ORDER BY indexstats.avg_fragmentation_in_percent desc
go

You could either run it against each database manually or you could make the main table of the query sys.databases. If you chose that approach you would want to add some extra info so you know what database is being referred to. Also, you would probably want to sort first by database, then fragmentation.

Or use the undocumented EXEC sp_MSforeachdb command...

There are some issues with that procedure. Check out this article. http://sqlblog.com/blogs/aaron_bertrand/archive/2010/12/29/a-more-reliable-and-more-flexible-sp-msforeachdb.aspx
