	Is it possible to run the same report across multiple databases ( all SQL SERVER with same set of tables structures) and aggregate the results within crystal reports and present to the user in a single report? Edited by mxr561 - 29 Oct 2009 at 9:29am

	If there's common data that you can link on, this should not be a problem. However, if you want a UNION of all of the information, it may be more challenging. I know that in Oracle I can setup "dblinks" that allow me to run a query in one database and pull data from another using the link. Is there anything like this in SQL Server? If so, you could set it up and write a command in Crystal that will run a union query to get the data you're looking for. -Dell

	I am thinking of using the sql command window to create a script that would traverse all available databases ( or a pre-defined set) and pull the data. The returned results will be grouped up based on a category and present to the user in a single report. Or the other option would be to create a stored procedure in one db which would do the above and return to the use just one result set.
