-- =============================================================================
-- 酒厂账单一次性修复（v4.0.6）
-- 库：生产 dukang_prod（也可在已同步的本地 dukang_haoke 先演练）
--
-- 规则（与代码一致）：
--   起点 WINERY_BILL_EPOCH_YMD = 2026-08-01
--   周期 WINERY_SETTLEMENT_PERIOD_DAYS = 3
--   出账日 8/4、8/7、8/10 … ；纳入窗口 [出账日-3, 出账日)
--   订单：status=COMPLETED AND pay_status=PAID
--         delivery_type IN ('LOCAL','CROSS_CITY','ON_SITE_PICKUP')
--   账期归属：completed_at（缺则 paid_at）的北京日历日
--   应付 = ROUND(实付合计 × 0.3, 2)；出账日无单仍留账单（无需打款）
--   已打款账单不改明细
--   起点之前已入账的订单（如 7/28 同城挂在 7/31）保持原账单，不迁到 8/4
--
-- 本脚本会：
--   1) 补现场提货等缺 completed_at 的已完成单
--   2) 按周期补齐出账日账单（含中间应付为 0 的空账）
--   3) 把未入账 / 挂错期（如 8/29）的同城、跨城、现场提货订单迁入对应出账日
--   4) 按明细重算未打款表头
--   5) 删除未打款、无明细、且非周期日的空账单（7/29、8/1、8/29 等）
--
-- 建议：先部署含「每 3 天出一期」的 API，再跑本脚本。
--       若必须先修数据：跑完后尽快发版，避免旧「每日只收 D-3 当天」任务回刷 8/28。
--
-- 用法（生产）：
--   mysql -u... -p dukang_prod < fix-winery-bills-v406.sql

-- 1) 现场提货等：支付即完成但未写 completed_at
UPDATE user_order
SET completed_at = paid_at

-- 2) 补齐周期出账日（8/4 起至「今天北京日」能落到的最后一张）

-- 6) 清掉误生成的非周期日空账单（有明细的如 7/31 保留；8/1 虽 MOD=0 但未满 3 天，仍删）
