MySQL锁表解决方案(亲测)

database

1,MySQL5.6版本之前的解决方案:

查询表锁定的SQL语句:

SELECT

r.trx_id waiting_trx_id,

r.trx_mysql_thread_id waiting_thread,

r.trx_query waiting_query,

b.trx_id blocking_trx_id,

b.trx_mysql_thread_id blocking_thread

FROM

information_schema.innodb_lock_waits w

INNER JOIN

information_schema.innodb_trx b ON b.trx_id = w.blocking_trx_id

INNER JOIN

information_schema.innodb_trx r ON r.trx_id = w.requesting_trx_id;

示例如下图:

2,MySQL5.7版本之后的解决方案:

MySQL5.7之后对锁表做了优化,查询表锁定的SQL语句比较简单,如下:

select * from sys.innodb_lock_waits;

示例如下图:

完结!!!
