mysql - SQL update date field when it contains a specific hour/minute

Question

I need a little help in updating my DATE fields on my db.
I have to update every DATE field that has a date in which hour, minute and seconds are "00:00:00".
The format of the date is "yyyy-mm-dd HH:mm:ss".
First question: is there a way to do this?
Second question: how can it be done?

Thank you very much for the help!


EDIT: I need to update that field with the same date with only hour (and minute, and seconds) changed. Thanks

Answer 2

update table_name
set column_name='your date'
where DATE_FORMAT(column_name, "%h/%i/%s") = "00:00:00"

またはSQLサーバーで

update table_name
set column_name='your date'
where 
CONVERT(VARCHAR(8), column_name, 14)='00:00:00'
