-- ============================================================
-- 紧急修复: 医生首页报 Unknown column 'p.submitter_id'
-- 时间: 2026-08-18
-- 说明:
--   biz_project_plan 加 submitter_id 列 + 索引 (代码已先行, DB 跟上)
--   biz_person.user_id 加 UNIQUE (LEFT JOIN 1:1 保证, 避免笛卡尔积)
--   ⚠️ 不 DROP 任何表 (DROP 走单独决策)
-- ============================================================

USE guoju0808;

-- ALTER 1: 给 biz_project_plan 加投稿人字段
ALTER TABLE biz_project_plan
  ADD COLUMN submitter_id BIGINT NULL COMMENT '投稿人用户ID (医生侧投稿归属, 经理/admin 录入为 NULL)';

-- ALTER 2: 给 submitter_id 加索引 (加速 WHERE 过滤)
CREATE INDEX idx_plan_submitter ON biz_project_plan(submitter_id);

-- ALTER 3: biz_person.user_id 加 UNIQUE (1:1 LEFT JOIN 无笛卡尔积)
-- 当前 dump 已确认 biz_person.user_id 无重复 (12 条数据, user_id 非空 2 条且 user_id=106/107 各一条)
ALTER TABLE biz_person
  ADD UNIQUE KEY uk_person_user_id (user_id);

-- 验证
