The table is something like:
CREATE TABLE
I've got a history table that performs a similar function. except in my
case I can have more than 1 active row. I put in an is_active column
and defined the type as a bool. an enum is actually a String in mysql,
which i didn't want to deal with. This table has only a few thousand
rows, so
