sqlserver查询锁以及解锁

刘泽宇

--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 (spid)

-- 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
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'
