インナーJoinに2列を掛ける

Question

ヘルプが必要です。

私は2つの列を掛けて、結果を新しい列（totalQty）に表示します。 TotalQty =（ITY00.CMPITQTY * MPOS_GP_InvTransaction.Quantity）

これはどのようにして達成できますか？

Select 
    MPOS_GP_InvTransaction.id, 
    MPOS_GP_InvTransaction.[Type], 
    MPOS_GP_InvTransaction.Vendor, 
    MPOS_GP_InvTransaction.Currency,ITY00.CMPTITNM, 
    MPOS_GP_InvTransaction.BatchId, 
    MPOS_GP_InvTransaction.UserId, 
    MPOS_GP_InvTransaction.ItemNo, 
    MPOS_GP_InvTransaction.SiteId, 
    ITY00.CMPITQTY, 
    MPOS_GP_InvTransaction.Quantity, 
    MPOS_GP_InvTransaction.IntegrationFlag 
From DB_37788.dbo.MPOS_GP_InvTransaction 
INNER JOIN TWCL.dbo.ITY00 ON ITY00.ITEMNMBR=MPOS_GP_InvTransaction.ItemNo 
Where (MPOS_GP_InvTransaction.ItemNo like '%-GTYR%') 
OR (MPOS_GP_InvTransaction.ItemNo like '%-JKOP%') 
And (MPOS_GP_InvTransaction.SiteId IN('MM-DC-ZZQW','MM-DC-TTYR')) 
And (MPOS_GP_InvTransaction.IntegrationFlag = 0)
