SqlServer表死锁的解决方法分享
前些天写一个存储过程,存储过程中使用了事务,后来我把一些代码注释掉来进行调试找错,突然发现一张表被锁住了,原来是创建事务的代码忘记注释掉。本文表锁住了的解决方法。
其实不光是上面描述的情况会锁住表,还有很多种场景会使表放生死锁,解锁其实很简单,下面用一个示例来讲解:1 首先创建一个测试用的表:
代码如下:
CREATE TABLE Test
(
TID INT IDENTITY(1,1)
)
2 执行下面的SQL语句将此表锁住:
代码如下:
SELECT * FROM Test WITH (TABLOCKX)
3 通过下面的语句可以查看当前库中有哪些表是发生死锁的:
代码如下:
SELECT request_session_id spid,OBJECT_NAME(resource_associated_entity_id)tableName
FROM sys.dm_tran_locks
WHERE resource_type='OBJECT '
4 上面语句执行结果如下:
spid :被锁进程ID。
tableName:发生死锁的表名。
5 只需要使用kill关键字来杀掉被锁的进程ID就可以对表进行解锁:
KILL 52

There was a problem, so I went to check the database and found that everything was normal. I first asked my colleagues if they had such a problem, and found that they did not, so I started my best part, facing Baidu. programming. The specific error message I started to solve was this, so I started Baidu error reporting: ERRORc.a.d.p.DruidDataSource$CreateCo
