PHP How to return datetime(6) from Mysql?

Question

When I query a dateTime(6) PHP is truncating my 6 fractional seconds.

Here is an example of my php code:

$sql = \'SELECT date FROM tbl\';
        $         


        

Answer 1

You can format it to include it. The %f includes the six-digit microseconds.

 SELECT DATE_FORMAT(date, '%Y-%m-%d %H:%i:%s.%f') FROM tbl

Answer 2

This bug was found in the Mysql (PECL) package of PHP and had been in an unresolved state for years. It was finally fixed in PHP v7.3.0.

Answer 3

The problem is with the PHP Adapter you are using to communicate with Mysql. As far as I can see you are using PDO adapter to fetch the query result. However, this adapter does not support fractional seconds (YYYY-MM-DD HH:MM:SS.F).

The PDO adapter supports YYYY-MM-DD HH:MM:SS and automatically formats the value of datetime columns to this format.

This is a bug in PDO adapter itself. Please find the link below for reference: http://grokbase.com/t/php/php-bugs/11524dvh68/php-bug-bug-54648-new-pdo-forces-format-of-datetime-fields

Answer 4

DateTime does not support split seconds (microseconds or milliseconds etc.)

Answer 5

in your case you might save the value in MySQL as VARCHAR and case / convert it to datetime when reading it.

I had the same problem and nothing helped me except converting

Answer 6

It's crazy this still isn't officially supported by mysqli in PHP 7.1, but anyway, here's a work around.

select concat(`DateTime6`)`DateTime6` from ...

Basically casting it as a string worked for me, as ugly as that is.
