DB::table('topics')->select('topics.*', 'b.username',

->orderBy('ord', 'desc')
->take($limit)->get();
连接查询取别名出错了
sqlstate[42s02]: base table or view not found: 1146 table 'startbbs.stb_users b' doesn't exist (sql: select stb_topics.*, stb_b.username, stb_b.avatar, stb_c.username as rname, stb_d.cname from stb_topics left join stb_users b on stb_b.uid = stb_topics.uid left join stb_users c on stb_c.uid = stb_topics.ruid left join stb_nodes d on stb_d.node_id = stb_topics.node_id where stb_topics.is_hidden = 0 order by ord desc limit 20)

最好的做法是把这SQL复制到数据库管理工具中执行下,看是否是你构造的有问题
从你构造的sql看,是因为别名中加上了表前缀'stb'
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。
