+-- ============================================
+-- 数据迁移说明
+-- ============================================
+-- 如果需要将旧字段数据迁移到新 JSON 配置字段，可以执行以下 SQL：
+-- 
+-- 1. 迁移自动投递配置（如果存在旧字段）
+-- UPDATE pla_account 
+-- SET deliver_config = JSON_OBJECT(
+--     'deliver_interval', 30,
+--     'min_salary', COALESCE(min_salary, 0),
+--     'max_salary', COALESCE(max_salary, 0),
+--     'page_count', COALESCE(page_count, 3),
+--     'max_deliver', COALESCE(max_deliver, 10),
+--     'filter_keywords', COALESCE(filter_keywords, JSON_ARRAY()),
+--     'exclude_keywords', COALESCE(exclude_keywords, JSON_ARRAY())
+-- )
+-- WHERE deliver_config IS NULL AND (min_salary IS NOT NULL OR max_salary IS NOT NULL);
+-- 
+-- 2. 迁移自动沟通配置（如果存在旧字段）
+-- UPDATE pla_account 
+-- SET chat_strategy = JSON_OBJECT(
+--     'chat_interval', COALESCE(chat_interval, 30),
+--     'is_chat_outsourcing', COALESCE(is_chat_outsourcing, 0),
+--     'time_range', JSON_OBJECT(
+--         'start_time', '09:00',
+--         'end_time', '18:00',
+--         'workdays_only', 1
+--     )
+-- )
+-- WHERE chat_strategy IS NULL AND (chat_interval IS NOT NULL OR is_chat_outsourcing IS NOT NULL);
+-- 
+-- 3. 迁移自动活跃配置（如果存在旧字段）
+-- UPDATE pla_account 
+-- SET active_actions = CONCAT('{"active_interval":', COALESCE(active_interval, 60), ',"actions":[]}')
+-- WHERE active_actions IS NULL OR active_actions = '' AND active_interval IS NOT NULL;
+
+-- ============================================
+-- 注意事项
+-- ============================================
+-- 1. deliver_config、chat_strategy、reply_config 使用 JSON 类型（MySQL 5.7+）
+-- 2. active_actions 使用 TEXT 类型（兼容已有数据库结构）
+-- 3. 如果 MySQL 版本低于 5.7，请将其他 JSON 类型改为 TEXT 类型
+-- 4. 执行前建议先备份数据库
+-- 5. 字段已存在时会自动跳过，不会报错
+-- 6. 如果需要迁移旧数据，请取消注释上面的数据迁移 SQL 并执行
