Manual talk:User groups table

How do I resolve the group names?
When I run "SELECT DISTINCT ug_group FROM user_groups;" I just get a list of numbers, e.g. 617070726f766564. How do I resolve these into the group names? Is there a separate lookup table, and if so which? The main article makes it sound like these should be text... Thanks!Tenbergen (talk) 14:33, 16 July 2015 (UTC)
