-- ============================================================

-- 1. 新增操作流水表

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='渠道服务订单操作流水';

-- 2. 订单主表新增汇总字段
ALTER TABLE `biz_channel_service_order`
  ADD COLUMN `total_recharge_amount` decimal(18,2) NOT NULL DEFAULT 0.00 COMMENT '累计充值总额' AFTER `channel_agreement_id`,
  ADD COLUMN `total_refund_amount` decimal(18,2) NOT NULL DEFAULT 0.00 COMMENT '累计退款总额' AFTER `total_recharge_amount`,
  ADD COLUMN `current_balance` decimal(18,2) NOT NULL DEFAULT 0.00 COMMENT '当前余额' AFTER `total_refund_amount`;

-- 3. 产品持仓表新增字段
ALTER TABLE `biz_channel_service_order_product`
  ADD COLUMN `total_buy_qty` decimal(18,4) NOT NULL DEFAULT 0.0000 COMMENT '累计购买数量' AFTER `buy_amount`,
  ADD COLUMN `total_unsubscribe_qty` decimal(18,4) NOT NULL DEFAULT 0.0000 COMMENT '累计退订数量' AFTER `total_buy_qty`,
  ADD COLUMN `current_qty` decimal(18,4) NOT NULL DEFAULT 0.0000 COMMENT '当前持有数量' AFTER `total_unsubscribe_qty`,
  ADD COLUMN `total_unsubscribe_amount` decimal(18,2) NOT NULL DEFAULT 0.00 COMMENT '累计退订金额' AFTER `current_qty`;

-- 4. 迁移现有充值记录到流水表
INSERT INTO `biz_channel_service_order_txn` (
  `id`, `service_order_id`, `txn_type`, `amount`, `txn_status`,
  `remark`,
  `finance_submit_by`, `finance_submit_time`, `finance_submit_remark`, `finance_submit_attachments`,
  `finance_confirm_time`, `finance_confirm_attachments`, `finance_remark`,
  `balance_before`, `balance_after`,
  `tenant_no`, `create_by`, `create_dept_id`, `create_time`, `update_by`, `update_time`, `del_flag`
)
SELECT
  REPLACE(UUID(),'-','') AS `id`,
  o.`id` AS `service_order_id`,
  'recharge' AS `txn_type`,
  o.`prepay_amount` AS `amount`,
  CASE
    WHEN o.`finance_confirm_time` IS NOT NULL THEN 'yqr'
    WHEN o.`finance_submit_time` IS NOT NULL THEN 'dqr'
    ELSE 'dsx'
  END AS `txn_status`,
  o.`remark`,
  o.`finance_submit_by`, o.`finance_submit_time`, o.`finance_submit_remark`, o.`finance_submit_attachments`,
  o.`finance_confirm_time`, o.`finance_confirm_attachments`, o.`finance_remark`,
  o.`balance_before`, o.`balance_after`,
  o.`tenant_no`, o.`create_by`, o.`create_dept_id`, o.`create_time`, o.`update_by`, o.`update_time`, o.`del_flag`
FROM `biz_channel_service_order` o
WHERE o.`order_type` = 'yfk' AND (o.`finance_submit_time` IS NOT NULL OR o.`prepay_amount` IS NOT NULL);

-- 5. 迁移退款记录到流水表
INSERT INTO `biz_channel_service_order_txn` (
  `id`, `service_order_id`, `txn_type`, `amount`, `txn_status`,
  `remark`,
  `finance_submit_by`, `finance_submit_time`, `finance_submit_remark`, `finance_submit_attachments`,
  `finance_confirm_time`, `finance_confirm_attachments`, `finance_remark`,
  `tenant_no`, `create_by`, `create_dept_id`, `create_time`, `update_by`, `update_time`, `del_flag`
)
SELECT
  REPLACE(UUID(),'-','') AS `id`,
  o.`id` AS `service_order_id`,
  'refund' AS `txn_type`,
  o.`refund_amount` AS `amount`,
  CASE
    WHEN o.`refund_finance_confirm_time` IS NOT NULL THEN 'yqr'
    ELSE 'dqr'
  END AS `txn_status`,
  o.`refund_remark` AS `remark`,
  o.`refund_apply_by` AS `finance_submit_by`,
  o.`refund_apply_time` AS `finance_submit_time`,
  o.`refund_remark` AS `finance_submit_remark`,
  o.`refund_attachments` AS `finance_submit_attachments`,
  o.`refund_finance_confirm_time` AS `finance_confirm_time`,
  o.`refund_finance_confirm_attachments` AS `finance_confirm_attachments`,
  o.`refund_finance_remark` AS `finance_remark`,
  o.`tenant_no`, o.`refund_apply_by` AS `create_by`, o.`create_dept_id`,
  COALESCE(o.`refund_apply_time`, o.`update_time`) AS `create_time`,
  o.`update_by`, o.`update_time`, o.`del_flag`
FROM `biz_channel_service_order` o
WHERE o.`refund_amount` IS NOT NULL AND o.`refund_amount` > 0;

-- 6. 回填主表汇总字段（yfk类型）
UPDATE `biz_channel_service_order` o
SET
  `total_recharge_amount` = COALESCE(o.`prepay_amount`, 0),
  `total_refund_amount` = COALESCE(o.`refund_amount`, 0),
  `current_balance` = COALESCE(o.`prepay_amount`, 0) - COALESCE(o.`refund_amount`, 0)
WHERE o.`order_type` = 'yfk' AND o.`prepay_amount` IS NOT NULL;

-- 7. 回填产品持仓表的累计字段
UPDATE `biz_channel_service_order_product` p
SET
  `total_buy_qty` = COALESCE(p.`buy_qty`, 0),
  `current_qty` = COALESCE(p.`buy_qty`, 0);
