I was not suggesting it for dates. The OP appeared to have a well-defined set
of strings in a VARCHAR field THAT is what I suggested ENUMs for!
What is the update frequency of those VARCHARs? If you're adding them often
or if you need to

Not sure I understand the
O, and the algorithm that I described only then works when the graph is
cycle-free. Otherwise it forever runs.
