PHP Mysqli从数据库中选择两个DISTINCT

Question

I am trying to fetch two different DISTINCT values from data base am not able to do that that gives me an error. I don't want both to be combined in as statement and fetch as one I need individual DISTINCT values.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DISTINCT AttendanceID from attendance_master where Attendence_taken_by !='admi' at line 1\\

My Query

$query = "select DISTINCT Standard , DISTINCT AttendanceID  from attendance_master where  Attendence_taken_by !='$admin'  and  SchoolID='$schoolid' and AttendanceDate >= '$tfrom_date' and AttendanceDate <= '$tto_date' ";

$result = mysqli_query($mysqli,$query)or die(mysqli_error($mysqli));
while($row=mysqli_fetch_array($result))
{
    echo "<table><tr>".$row["Standard"]."</tr><tr>".$row["AttendanceID"]."</tr></table>";
}

Answer 1

Syntax of DISTINCT is

SELECT DISTINCT column_name,column_name
FROM table_name;

So change your query with

$query = "select DISTINCT Standard , AttendanceID  from attendance_master.....

Instead of assign direct value use bind_param
