How to trigger the "error" callback in JQuery AJAX call using in PHP

Question

I have PHP code snippet the following:

if (!($result = mysql_query($query, $link))) {
   die("Invalid SQL query: " . $query);
}

And I have JQuery code snippet the following:

$.ajax({
        url: "....search.php", 
        data: ...,

        async: false, //to trigger error alert

        success: function(xml) {
            ...
        },

        error: function(xml) {
            foundError = true;
        },

        dataType: "xml"
    });

if(foundError) {
        setProgress("Could not complete the search because an error was found", ProgressBar.ERROR);
}

Is it possible to have the die call trigger JQuery error function callback? If not, how would I trigger it otherwise?

Try this:

if (!($result = mysql_query($query, $link))) {
   header("HTTP/1.1 404 Not Found");
}

Choose the error appropriate for your application
