Convert mysql DATETIME column to epoch seconds

问题

I have a column mysql datetime that is in DATETIME format.

Is there a way to SELECT this column in epoch seconds? If not, what would be the best way of converting the datetime format to epoch seconds? What type of field would be the best to capture this?

回答1:

Use MySQL's UNIX_TIMESTAMP function

回答2:

You can use :

SELECT UNIX_TIMESTAMP(yourfield) FROM yourtable;

And for UPDATE, the invers function is : FROM_UNIXTIME(...)
