problem with sorting an html php mysql table
Question
I'm a learning programmer and I have an question.
I have an Html table on my website, and I fill it with my data from my MySql.
Now I want to sort my Table Datewise, so I want the nearest date at the top of the table.
How do I do that ( My Date format is [dd.mm] no years )
With the ORDER BY method the 01.11 is for example the first entry and not after the 23.10.
My Code:
I hope you could help me because I am not getting it.

Convert your date column into datetime and use the below query.
$sql = " SELECT * FROM lll
ORDER BY convert(datetime, Ende , 104) ASC ";
Here, 104 stands for dd.mm format
Method 2:
$sql = "SELECT * FROM lll
ORDER BY STR_TO_DATE(Ende ,"%d.%m") ASC";

由于您只有一天和一个月，因此可以尝试一下。
SELECT * FROM lll ORDER BY STR_TO_DATE(Ende,'%d.%m') DESC
