Returning the write timestamp

A table contains a timestamp representing the date and time that a write occurred to a column. Using the writeTime function in a SELECT statement returns the timestamp that the column was written to the database. The output of the function is microseconds. Counter column writetime is milliseconds.

  • Retrieve the date/time that the value Paolo was written to the firstname column in the table cyclist_points. Use the WRITETIME function in a SELECT statement, followed by the name of a column in parentheses:

    SELECT WRITETIME (firstname) FROM cycling.cyclist_points WHERE id=220844bf-4860-49d6-9a4b-6b5d3a79cbfb;

    The writetime output in microseconds converts to Wed, 24 Jun 2015 01:12:05 GMT.
