-- 注意事项
|
|
-- ============================================
|
|
-- 1. 此脚本使用IF NOT EXISTS语法，可重复执行而不会报错
|
|
-- 2. 索引创建会占用额外的磁盘空间，提高写操作开销，但显著提升查询性能
|
|
-- 3. 建议在低峰期执行此脚本
|
|
-- 4. 执行后建议监控应用性能，确认优化效果
|
|
-- 5. 对于MySQL数据库，索引创建命令可能略有不同
|
|
-- ============================================
|
|
|
|
-- MySQL版本的部分索引创建语法示例（仅供参考）
|
|
-- ALTER TABLE users ADD INDEX idx_users_userId (userId);
|
|
-- ALTER TABLE users ADD INDEX idx_users_phoneNumber (phoneNumber);
|
|
-- 以此类推...
