-- =============================================================================
-- 教务同步视图生产验证脚本
-- 用途：部署 vw_jw_student_export / vw_jw_student_change_export 后执行
--
-- 用法：
--   mysql -h <host> -u root -p hzdyjs_xg < docs/数据库脚本/2026-09-02-verify-jw-export-views.sql
--
-- 说明：
--   * 脚本仅 SELECT，不修改数据
--   * 若某段报错，说明对应视图或依赖表/字段异常
--   * 「培养层次疑似中文」> 0 表示仍返回中文名称，需核对视图是否已更新
