Somebody asked about this 8 years ago (link is here), so I'm guessing I just can't figure out the tool. How do you create a query table which persists inside of a File GeoDatabase? The Make Query Table tool is accessible within ArcCatalog and runs, it just does not seem to put the result anywhere? (It does work in ArcMap as advertised, it is just a little easier if staff can drag the table into their map instead of rerunning the tool every time they want to do something slightly different on a new map)
