我正在使用以下查询从10个表中获取数据，它工作正常，但速度很慢，有什么方法可以优化查询。
查询：选择emi.emi_due_date，users.usr_mobile，users.usr_id，concat_ws（“”，users.usr_fname，users.usr_mname，users.usr_lname）作为借款人，users.usr_status，users.usr_curnt_city，users.usr_email， emi.loan_id，emi.emi_show_date，sum（emi.emi_amount）-sum（ifnull（emi.settled_amount，0））作为due_amount，cb.cb_type，blr.bloan_collection_executive_id，blr.pp_allow，blr.bloan_legal_team_us，blcon。 （“”，cp.cp_fname，cp.cp_lname）作为cp_name，cp.cp_mobile，cp.cp_firm_name，cp.cp_type，bg.guarantor_name，bg.guarantor_contact，pl.ecs_date，pd.p2p_date，
（从借方付款主的WHERE贷款ID = emi.loan_id的ID限制为0,1的订单中选择工具）作为last_pmode，
（SELECT IFNULL（DATE_FORMAT（emi_show_date-INTERVAL 1 MONTH，“％m-％Y”），“”）来自emi AS e WHERE e.loan_id = emi.loan_id和e.emi_status <2 ORDER by e.emi_show_date ASC限制1）为已付费，
（将“ browser_payment_master中的付款日期选择为bp，其中bp.loan_id = emi.loan_id按bp.id dec限制1排序）作为last_emi_paid FROM emi AS emi
通过emi.loan_id = blr.bloan_id进行INNER JOINrower_loan_reg_requests AS blr
INNER JOIN用户AS用户ON users.usr_id = blr.bloan_user_id
INNER JOIN借入者rower_loan_disbursed_funds作为blf ON blf.df_bloan_id = emi.loan_id
左加入channel_partners AS cp ON cp.cp_id = users.usr_cp_referral_id
向左保留借贷人_借款人贷款作为pl.pl_bloan_id = emi.loan_id
左联接collection_bucket AS cb在cb.cb_loan_id = emi.loan_id和cb.cb_status = 1
以左bg.guarantor_borrower_id = users.usr_id的身份向左加入clienter_guarantors AS
以pd.p2p_loan_id = emi.loan_id和pd.p2p_status = 1上的pd身份加入p2p_dates
其中emi.emi_status <2和emi.emi_amount！= 0
并且（从burrower_payment_master中选择count（*）作为pm WHERE pm.loan_id = emi.loan_id
AND MONTH（pm.payment_date）=“'.date（'m'）。'” AND YEAR（pm.payment_date）=“'date（'Y'）。'”）= 0
AND（并且从s.settlement_date中选择s.settlement_date作为s.loan_id = s.loan_id限制1的日期）！=“”
按emi.loan_id分组按emi.loan_id desc排序
