Mysql事务：释放当前锁

查看当前运行事务：
SELECT
     a.trx_id,
     a.trx_state,
     a.trx_started,
     a.trx_query,
     b.ID,
     b.USER,
     b.DB,
     b.COMMAND,
     b.TIME,
     b.STATE,
     b.INFO,
     c.PROCESSLIST_USER,
     c.PROCESSLIST_HOST,
     c.PROCESSLIST_DB,
     d.SQL_TEXT
FROM
     information_schema.INNODB_TRX a
LEFT JOIN information_schema.PROCESSLIST b ON a.trx_mysql_thread_id = b.id AND b.COMMAND = 'Sleep'
LEFT JOIN PERFORMANCE_SCHEMA.threads c ON b.id = c.PROCESSLIST_ID
LEFT JOIN PERFORMANCE_SCHEMA.events_statements_current d ON d.THREAD_ID = c.THREAD_ID;

查看当前运行事务对应进程id：
select concat('KILL ',id,';') from information_schema.processlist p inner
join information_schema.INNODB_TRX x on p.id=x.trx_mysql_thread_id where db='DB001';
