MySQL表日期更新在表格中给出00/00/0000 12:00:00 am格式

I am updating datetime column in one table, but when update the column date save as 00/00/0000 12:00:00 am.

Here is Mysql query

update b_tasks set DEADLINE='28/12/2017 01:30:00 pm' where ID=4666 AND TITLE LIKE 'Perform demo%'. And in PHP look like

$sql='update b_tasks set DEADLINE="'.$dtformat.'" where ID="'.$tid1.'" 
AND TITLE LIKE "Perform demo%"';

$sql="update b_tasks set DEADLINE=STR_TO_DATE('".$dtformat."','%d/%m/%Y %h:%i:%s %p') where ID='".$tid1."' 
AND TITLE LIKE 'Perform demo%'";

Try above query.

You need to use STR_TO_DATE, which convert your given format string to date.

If you don't want to use this function you can go with default format 'yyyy-mm-dd HH:MM:SS'

This will help you.
