WP_Query - meta fields numeric

Question

I'm having trouble with the code below. Attempting to do a query against meta data stored with the posts, in the mls post type. I think I know what the issue is, but not how to fix it. I am guessing it has something to do with the value being stored as a string. I've searched and found other people confused about this, but not a solution. Here are two examples I've attempted with no luck.

<?php $args = array(
        'post_type' => 'mls',
        'meta_query' => array(
            relation => 'AND', 
            array(
                'key' => '_city',
                'value' => 'Clarkson',
                'compare' => '='
            ),
            array(
                'key' => '_price',
                'value' => '200000',                    
                'type' => 'numeric',
                'compare' => '>='
            )
            //array(
            //  'key' => '_price',
            //  'value' => array( 200000, 1000000 ),
            //  'type' => 'numeric',
            //  'compare' => 'BETWEEN'
            //)
        )
    ); ?>

Try using the Docs here. I tried the same thing and it worked for me.

Answer 2

Maybe I'm wrong but you are missing query relation...

<?php $args = array(
        'post_type' => 'mls',
        'meta_query' => array(
            relation => 'AND', 
            array(
                'key' => '_city',
                'value' => 'Clarkson',
                'compare' => '='
            ),
            array(
                'key' => '_price',
                'value' => '200000',                    
                'type' => 'numeric',
                'compare' => '>='
            )
            //array(
            //  'key' => '_price',
            //  'value' => array( 200000, 1000000 ),
            //  'type' => 'numeric',
            //  'compare' => 'BETWEEN'
            //)
        )
    ); ?>
