原sql语句为：
SELECT * from ( SELECT DISTINCT *, year( from_unixtime(time ) ) year, month( from_unixtime(time ) ) month FROM A表 WHERE id = 1) as a WHERE is_del =0 AND year = 1 AND month = 1 order by time DESC
现在我想关联B表.如何查询？
A表.id=B表.id
SELECT * from ( SELECT DISTINCT *, year( from_unixtime(time ) ) year, month( from_unixtime(time ) ) month FROM A表 WHERE id = 1) as a , B表 b WHERE a.id=b.ai and is_del =0 AND year = 1 AND month = 1 order by time DESC
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
