根因:生产库 aihr_practice_assignment.ext_party_id 继承表级默认 utf8mb4_0900_ai_ci, 与 aihr_practice_question_feedback.ext_party_id (utf8mb4_general_ci) 冲突, 导致 AihrPracticeSeedService.assignments() 子查询抛 ERROR 1267, /me 接口异常,员工端误报'人力系统未匹配'。 修复: - ALTER TABLE 对齐 ext_party_id 列排序规则为 utf8mb4_general_ci - 已在生产热修复并验证,查询恢复正常 - 本地 docker 容器复现+修复验证通过 - 前端无需改动,H5 重新构建确认流程无误 影响范围: - 仅 aihr_practice_assignment 表单列 MODIFY - 保留所有数据与索引,无业务中断 - 回滚材料在 /opt/wygj/backups/release-20260718005151 遗留: - position 页异常场景退出入口待下轮补充(P1) - schema 规范:后续 DDL 显式声明 COLLATE,不依赖表级默认 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

-- Emergency collation alignment for aihr_practice_assignment.
|
|
-- Root cause: production database uses utf8mb4_general_ci for tenant_id column
|
|
-- (inherited from RuoYi base schema), but ext_party_id column lacks explicit
|
|
-- COLLATE clause and inherits utf8mb4_0900_ai_ci from the table DEFAULT.
|
|
-- When the subquery JOIN in AihrPracticeSeedService.assignments() compares
|
|
-- aihr_practice_assignment.ext_party_id = aihr_practice_question_feedback.ext_party_id,
|
|
-- MySQL rejects the implicit collation coercion with error 1267.
|
|
--
|
|
-- Fix: align ext_party_id column collation with the canonical tenant_id collation
|
|
-- already in use by the target database (utf8mb4_general_ci in production).
