Relate Geoprocessing Tool

[JeffPapirtis]

Is there a Geoprocessing tool that can be used within Model Builder, or within a Python Script?  I am aware of how to acomplish this within ArcMap, but I am working on automating selected related records from one table to another.

Thanks,
Jeff

There is a keyfile select custom tool in ArcScripts by Bruce Harold that does this.

You might be able to manage a similar goal using the MakeQueryTable that can do a more complex database query than a simple join.
