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

I have created my own query for your problem:

SELECT HOUR(`colname`) * 3600 + MINUTE(`colname`) * 60 + SECOND(`colname`)
FROM widgets
WHERE id = 1;

• Use id = 1 if you have to take a specific row.
• The output will be in seconds.
