Storing microseconds in MySQL: which workaround?

Question

we\'re writing a scientific tool with MySQL support. The problem is, we need microsecond precision for our datetime fields, which MySQL doesn\'t currently support. I see at leas

Answer 1

How about splitting the date parts into a date-only part, and microseconds from midnight? There are less than 2^64 microseconds in the day. Then cluster the table on {date, microsecond}.

I would guess, though I don't know your data, that certain queries would be fine with day-level accuracy -- 'experiments in 1964' doesn't need to worry about microseconds.
