show OPEN TABLES where In_use > 0;

SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCK_WAITS;

select * from information_schema.INNODB_TRX;

select * from information_schema.PROCESSLIST WHERE ID = '661499';

show engine innodb status;

show PROCESSLIST;

select thread_id,event_name,lock_time,digest_text,current_schema from events_statements_history_long where thread_id=1632 ;

-- 设置打印general_log，所有mysql日志

show variables like '%general%';

set global general_log=1;
或
set global general_log=ON;
