looking for a tool

I am trying to find some sort of tool that will allow me to give a parent primary key entry, and the tool with either export or generate sql to create the entire object, the parent and all children, to another database. Does anyone know of such a tool? I am sure it could be written, but I dont want to re-create the wheel if it is not necessary.
