MYSQL - datetime to seconds

Question

I wasn\'t able to find out (googling, reading mysql reference manual) how to get value of DATETIME in seconds in MySQL.

I dont mean to extract secon

Answer 1

The function UNIX_TIMESTAMP(datetime) returns the unix time, which happens to be the number of seconds since 1-Jan-1970 0000 UTC. That may be what you need, but not if you're dealing with dates of birth, historical dates, or dates after 2037.
