Question

SELECT A.cl_id, A.cl_name, A.number_of_orders, B.Dispatch 
FROM (
    SELECT CL_Clients.cl_id, CL_Clients.cl_name,COUNT(*) AS number_of_orders 
    FROM CL_Clients,CLOI_ClientOrderItems 
    WHERE CL_Clients.cl_id = CLOI_ClientOrderItems.cl_id 
    GROUP BY CL_Clients.cl_name,CL_Clients.cl_id 
    ) A 
INNER JOIN (
    SELECT CL_Clients.cl_id,count(*) AS Dispatch
