試試這個：

SELECT a.ClassCode,a.Description,d.BusinessUnit,d.BUDes,d.Department,c.Total 
FROM tbl_fa_asset_reg_mas_b_class a 
JOIN 
tbl_fa_asset_reg_mas_c_group b 
ON a.ClassCode = b.AssetClass 
JOIN 
(SELECT COUNT(c.AssetGroup)AS Total,AssetGroup 
    FROM tbl_fa_asset_reg c 
GROUP BY c.AssetGroup)c 
ON c.AssetGroup = b.AssetGroup 
JOIN tbl_a_comp_f_bu d 
ON d.BusinessUnit = c.BusinessUnit 
GROUP BY 
a.ClassCode, a.Description, d.BusinessUnit, d.BUDes, d.Department 
ORDER BY ClassCode ASC
