I hope someone can help me with this query. Basically I have two queries that I want to "combine". I want the second query as an extra column along with the first query. The first one is this :

SELECT t_Item_Storage_Location.Storage_Loc_Nbr, 
t_Storage_Location.Storage_Loc_Type_Code, 
Count(t_Load.Load_Id) AS CurrentLoadCount,
t_load.MMM_Id_Nbr

FROM t_Load INNER JOIN (t_Storage_Location INNER JOIN t_Item_Storage_Location ON 
t_Storage_Location.Storage_Loc_Nbr = t_Item_Storage_Location.Storage_Loc_Nbr) ON 
(t_Load.Storage_Loc_Nbr = t_Item_Storage_Location.Storage_Loc_Nbr) 
AND (t_Load.MMM_Id_Nbr = t_Item_Storage_Location.MMM_Id_Nbr)


where ((((t_Item_Storage_Location.MMM_Id_Nbr) Between '702004%' And '702011%') 
AND ((t_Item_Storage_Location.Storage_Loc_Nbr) Like '%A') 
AND ((t_Storage_Location.Storage_Loc_Type_Code)='CD') 
AND ((t_Load.Active_Status_Ind)='A') 
AND ((t_Load.QC_Status_Code) Like 'R%') 
AND ((t_Load.MMM_Facility_Code)='MC')) 
OR (((t_Item_Storage_Location.Storage_Loc_Nbr) Like '%B'))
OR (((t_Item_Storage_Location.Storage_Loc_Nbr) Like '%C')) 
OR (((t_Item_Storage_Location.Storage_Loc_Nbr) Like '%D')) 
OR (((t_Item_Storage_Location.Storage_Loc_Nbr) Like '%E'))

)
GROUP BY t_Item_Storage_Location.MMM_Id_Nbr,
t_Item_Storage_Location.Storage_Loc_Nbr, 
t_Storage_Location.Storage_Loc_Type_Code,
t_Load.MMM_Facility_Code,
t_load.MMM_Id_Nbr

HAVING
Count(t_Load.Load_Id)<4

The second one, is based on the t_load.MMM_Id_Nbr of the first one. Basically I want a count of all the loads with that mmm_id_nbr.

SELECT count(Load_ID) as LoadCount, MMM_Id_Nbr, storage_Loc_Nbr
FROM t_load 
WHERE QC_Status_Code like 'R%' and mmm_Facility_Code ='MC' and Active_Status_Ind='A'
GROUP by MMM_Id_Nbr, storage_loc_Nbr
