教你使用sqlserver:查询锁住sql语句以及如何解锁方法
查看被锁表语句
–查看被锁表：
SELECT
request_session_id spid,
OBJECT_NAME(
resource_associated_entity_id
) tableName
FROM
sys.dm_tran_locks
WHERE
resource_type = ‘OBJECT’
ORDER BY request_session_id ASC
–spid 锁表进程
–tableName 被锁表名
–根据锁表进程查询相应进程互锁的SQL语句
DBCC INPUTBUFFER (249)
解锁语句
— 解锁：
DECLARE
@spid INT
SET @spid = 52–锁表进程
DECLARE
@SQL VARCHAR (1000)
SET @SQL = ‘kill ‘ + CAST (@spid AS VARCHAR) EXEC (@SQL)
生成解锁SQL语句
–生成解锁SQL
SELECT
DISTINCT ‘DECLARE @spid INT SET @spid = ‘,request_session_id,’ DECLARE @SQL VARCHAR (1000) SET @SQL = ”kill ” + CAST (@spid AS VARCHAR) EXEC (@SQL);’ as s
FROM
sys.dm_tran_locks
WHERE
resource_type = ‘OBJECT’ –spid 锁表进程
–tableName 被锁表名
总结
