Here is my problem, I have a MySQL database with table in it that has 4 columns: ID, Owner, Address, Legal. And I also have an ArcGIS GDB that has a parcel layer that has in it a PID field. I am looking for a way to join this MySQL table and the ArcGIS GDB into a new GDB with all of the information from both in Python using arcpy. The PID field and the ID field match up, I am just not finding a way to to a join between a MySQL table and the GDB. Any help would be appreciated.

Once you use it to create a connection you can use that in your ArcMap MXD or ArcPY script to join to your GDB. Here's the manual on the ArcPY syntax for joins:
