Integration Services :: Using Database Name As Parameter In OLE DB Source Command Text?

I'm using following command to populate my OLE DB Source. I have two of those in each Data Flow in my package. One of the OLE DB Sources points to my source database the other to the destination. In order to limit the number of rows I use the WHERE clause below. The [EnergyMiserFSRLive] being the the name of the source database. The Connection manager points to the destination database.

I would like an elegant way to replace  [EnergyMiserFSRLive] with a parameter which I can reuse in each of my many data flows rather than use this hard coded value [EnergyMiserFSRLive].In particular I'm after the syntax of the below query that uses the parameter for [EnergyMiserFSRLive].

SELECT [SitesId]
      ,[SiteName]
      ,[FilePrefix]
      ,[City]
      ,[StateProv]
      ,[Country]
  FROM [Sites]
WHERE SitesId >= (SELECT MIN(SitesId) FROM [DBNameFSRLive].[dbo].[Sites])
  ORDER BY [SitesId]
