Re: storing username

[Peter Brawley]

Do the arithmetic. An enum column with 5 values spread more or less equally across, say, 50k rows will have 10k dupes of each value. An index on that will speed up nothing.

Which you could insert with from_unixtime(...) and retrieve with unix_timestamp(...). IAC int(50) is gibberish.

But why reinvent the wheel? There are lots of robust appointment schemas, see http://www.databaseanswers.org/data_models/.
