php - Why does MySql format datetime microseconds as .000000? -


i not sure why, when new record added database table, format of time followed period , 6 zeros. example 

2014-03-24 11:00:03.000000

i using following php code date , time

date("y-m-d h:i:s")

the record added database via array, passed through following function:

$record = array( 'date' => date("y-m-d h:i:s") );

function:

$data   = '`' . implode('`, `', array_keys($record)) . '`'; $values = '\'' . implode('\', \'', $record) . '\''; mysql_query("     insert `". $table ."` ($data)     values (". $values .") ");

i don't think mysql supports microseconds, ideally remove makes table messy. suggestion on how can remove microseconds?

if care format of datetime value when returned, use date_format():

select date_format(col, '%y-%m-%d %h:%i;%s') yyyymmss_hhmmss

don't depend on database returning value in particular format, if want in format.

as question of "why" mysql this. because can. database free return date , datetime values likes. creators of mysql chose general format column contain fractional seconds. key point shouldn't depend on this, if want particular format. mysql has excellent functional support formatting dates , reading dates strings.
