hope this fix your issue I have a little problem with my select query. If I input a string of numbers (int) and the user with that "username" exists, I get a result named $resultw. But if I enter in the form a string with letters (varchar) and a user have this username in my database it didnt works and I didnt get any (error) message. What could happen that?
code :
$sql = "SELECT id, email, username 
FROM user
WHERE username = '$uinput'";

This might help you With my code below I convert XML to mySQL and after that I search (from a form) and it returns me the id of the entry that the term was found in. , Maybe setting an header in the result page
code :
<?php header('Content-type: text/html; charset=UTF-8') ;?>

I hope this helps . I have a wordpress query to search for the initial letter of the name tag as follows. , Put single quotes around '%s' in your query statement:
code :
function restrict_by_first_letter( $where, $qry ) {
    global $wpdb;
    $sub = $qry->get('substring_where');
    if (!empty($sub)) {
        $where .= $wpdb->prepare(
        " AND SUBSTRING( {$wpdb->posts}.post_title, 1, 1 ) = CONVERT('%s',char) ", $sub
        );
    }
    return $where;
}

add_filter( 'posts_where' , 'restrict_by_first_letter', 1 , 2 );

I hope this helps you . Here is the code I am running. The strange thing is if I run the exact same query in PHPMyAdmin it runs perfectly. , It looks and sounds like your "error" is on this line:

wish of those help If x contains only numbers, XPath interprets the value as numeric. If x also contains letters, it's interpreted as a string and needs to be quoted:
