php - Comparing meta_query with array does not work -

in database have following entry @ order_products:

a:1:{i:0;s:6:"1234";} 

i try show orders product_id 1234:

$orders = array(      'post_type' => 'orders',     'year' => $year,     'monthnum' => $month,     'day' => $day_minus, 'meta_query' => array (             array (                 'key' => 'order_status',                 'value' => array( 'bill', 'back', 'pay', 'completed' ),                 'compare' => 'in'              ),         array (                 'key' => 'order_products',                 'value' => array('1234'),                 'compare' => '='             )         )   );   $the_query = new wp_query( $orders );  $total_orders = $the_query->found_posts; 

with

compare => 'like'  

it working if there more single "1234" product, these orders showing (for example product 1234, 1235 , 1256). want show if alone.

i think issue comparing array.

compare => "="  

is there way compare single item array "=" ?

give value numeric form 'value' => array ( 79, 200, 124) example below

 //note check relation comment , uncomment form  $args => array( 'relation' => 'and',    array (             'key' => 'order_status',             'value' => array( 'bill', 'back', 'pay', 'completed' ),             'compare' => 'in'    ),  array(     'key' => 'order_products',     'value' => array ( 79, 200, 124)     'compare' => '=',     'type' => 'numeric'  ) ) 

any problem welcome.
