以下查询返回所有客户端的记录,会话$_SESSION['client_id']值为3
查询工作正常,但它返回所有客户端的记录。我想在所有SELECT Clauses上应用会话值。

SELECT mrk_lat,client_id,mrk_lng ,engine_status ,created_date,live_fuel,
     (SELECT count(driver_id) FROM we_drivers) as total_drivers,
     (SELECT count(veh_id) FROM we_vehicles) as total_veh,
     (SELECT count(veh_status) FROM we_vehicles WHERE veh_status=1) as run_veh,
     (SELECT count(veh_status) FROM we_vehicles WHERE veh_status=0) as stop_veh,
     (SELECT client_id FROM we_clients WHERE client_id =" .  $_SESSION['client_id'] . ") 
            FROM `we_vehicles_coordinates`
