            AND DATE(t.f_txn_datetime) = '2016-03-08'
            AND t.f_trx_type = '1240/110'
    GROUP BY MERCHANT) S,
    bijlipay.bij_merchant M,
    bijlipay.bij_address AD,
    bijlipay.bij_codeset C,
    bijlipay.bij_device_allocation A

    M.id_merchant = S.merchant
        AND AD.id_address = M.mercinfo_permanent_address
        AND C.codename = M.mercinfo_mcc
        AND A.merchant_id = S.merchant
GROUP BY S.MERCHANT;
