I can`t use these sql :
select count(1) from(select * from t_order) c ;
select count(1) from (select u.id , count(1) from t_order o inner JOIN t_user u on o.uid=u.id GROUP BY u.id )c ;
select count(1) from (select count(1) from(select * from t_order) c )b ;

Hi @fengchao-GitHub ~
Could you try whether other statements are effective? Such as "select * from t_order" or "SELECT COUNT(*) FROM t_order".
Or could you try to check the proxy status by viewing the proxy log?
