无法使用不同的值获得2个值

Question

here is what i used

<?php     
$cat_query = mysqli_query($connection, "SELECT DISTINCT category,bid FROM banners WHERE category != 'None'");
?>

but still i am getting duplicates records can anyone help me out as i want too get bid and category as well both

Answer 1

There is no way you can get Distinct Categories with bid. You should either use Distinct Categories alone or sort your data based on required bid.
