TIMESTAMP()
Synopsis
TIMESTAMP(date,time)
This function merges the date and time from given strings or
columns that contain date and time data separately; the result is
returned in yyyy-mm-dd hh:mm:ss format. If
only the date or only the time is given, the function will return
zeros for the missing parameter. It’s available as of version 4.1.1 of
MySQL. Here is an example:
SELECT TIMESTAMP(appt_date, appt_time) AS 'Appointment' FROM appointments LIMIT 1; +---------------------+ | Appointment | +---------------------+ | 2008-07-16 11:13:41 | +---------------------+
