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

If you say that the most popular queries are time base, I would recomend going with a single column that stores the time as in your first option.

You could pick your own epoch for the application, and work from there.

This should simplify the queries that needs to be written when searching for the time intervals.

Also have a look at 10.3.1. The DATETIME, DATE, and TIMESTAMP Types

However, microseconds cannot be stored into a column of any temporal data type. Any microseconds part is discarded. Conversion of TIME or DATETIME values to numeric form (for example, by adding +0) results in a double value with a microseconds part of .000000
