+
+-- ============================================
+-- 9. 关联查询优化索引
+-- ============================================
+
+-- 9.1 course_signs 关联 users 优化
+-- 已通过 user_id 索引优化
+
+-- 9.2 users 关联 course_signs 优化
+-- 需要在 course_signs 表已有 user_id 索引
+
+-- 9.3 companies 关联 users 优化
+-- 需要在 users 表已有 company_id 索引
+
+-- 9.4 courses 关联 course_types 优化
+-- 需要在 courses 表已有 type 索引
+
+-- ============================================
+-- 10. 特殊查询优化建议
+-- ============================================
+
+-- 10.1 JSON 字段查询优化
+-- companies.project_users 字段（JSON）无法直接建立索引
+-- 建议：如果 investDate 查询频繁，考虑单独建立 invest_dates 表或字段
+
+-- 10.2 LIKE 查询优化
+-- 对于 '%关键词%' 类型的 LIKE 查询，无法使用普通索引
+-- 建议：
+-- 1. 如果可能，改为前缀匹配 '关键词%' 可以使用索引
+-- 2. 考虑使用全文索引（FULLTEXT）：
+ALTER TABLE `companies` 
+ADD FULLTEXT INDEX `ft_company_tag` (`company_tag`);
+
+ALTER TABLE `users` 
+ADD FULLTEXT INDEX `ft_company_name` (`company_name`);
+
+ALTER TABLE `users` 
+ADD FULLTEXT INDEX `ft_from` (`from`);
+
+-- 10.3 日期范围查询优化
+-- 对于 start_date/end_date BETWEEN 查询，确保日期字段有索引
+-- 对于 orWhereBetween 查询，MySQL 可能无法同时使用两个索引
+-- 建议：如果性能问题，考虑拆分为两个查询 UNION
+
+-- ============================================
+-- 11. 索引使用说明
+-- ============================================
+
+-- 11.1 索引创建顺序
+-- 建议按照表的数据量和查询频率，优先创建高频查询的索引
+
+-- 11.2 索引维护
+-- 定期使用 EXPLAIN 分析查询计划，确认索引被正确使用
+-- 示例：EXPLAIN SELECT * FROM course_signs WHERE status=1 AND course_id IN (1,2,3);
+
+-- 11.3 索引监控
+-- 使用以下查询监控索引使用情况：
+-- SELECT * FROM sys.schema_unused_indexes;
+-- SELECT * FROM performance_schema.table_io_waits_summary_by_index_usage;
+
+-- 11.4 注意事项
+-- 1. 索引会占用存储空间，增加写入成本
+-- 2. 不要过度索引，每个表建议不超过 5-7 个索引
+-- 3. 复合索引的顺序很重要，将选择性高的字段放在前面
+-- 4. 定期分析表，更新统计信息：ANALYZE TABLE table_name;
+
+-- ============================================
+-- 12. 性能优化建议
+-- ============================================
+
+-- 12.1 查询优化
+-- 1. 避免在 WHERE 子句中使用函数
+-- 2. 使用 EXISTS 替代 IN（当子查询结果集较大时）
+-- 3. 合理使用 JOIN，避免过度嵌套
+
+-- 12.2 分页优化
+-- 对于大数据量分页，考虑使用游标分页替代 OFFSET
+
+-- 12.3 缓存策略
+-- 对于统计类查询，考虑使用 Redis 缓存结果
+
+-- ============================================
+-- 索引创建脚本执行顺序建议
+-- ============================================
+
+-- 1. 先创建核心表索引（course_signs, courses, calendars）
+-- 2. 再创建关联表索引（companies, users）
+-- 3. 最后创建辅助表索引（stock_companies, history_courses）
+
+-- 执行前请备份数据库！
+-- 建议在业务低峰期执行索引创建操作
