Hi all,
I have a datatable with 10 columns and the 9th column is date which is to be sorted in descending order. This gets sorted as expected. For a certain condition, the value should be provided with hyperlink. When i provide hyperlink, then it is sorting wrongly.

<td class="tablecntcolum"><a href='.$logFilePath.'target="_new">'.$field_monitor_values[$i[10].'</a></td>

Thenfinal output is something like this :
30-Apr-17
30-Apr-17
15-Sep-16
15-Sep-16
15-Sep-16
15-Sep-16
15-Sep-16
15-Oct-16
05-May-17
05-May-17

What I have tried:

var poltable = $('#pol_table').DataTable( {
       order: [[ 9, 'desc' ]],//sorting based on 9th column
       pageLength: 50,
       autoWidth: true
   });

I think in the query it will be wrong.
I was facing same issue because
you should give tablenm.date column name in query LIKE
SELECT * FROM student WHERE id='767' GROUP BY student.id ORDER BY student.date asc

That is SQL and nothing to do with the original question. It also doesn't make any sense

Your problem is rather obvious: the sort is perfect! You see date, the computer sees characters.

You need to sort them either in your SQL query before you convert the datetime field to a string (unless you horribly store dates as strings!) or maybe try a more useful date format:

YYYYMMDD will sort correctly as characters . . . that's a numerical month, by the way, or you'll get screwed up again.
