一、查看当前锁定的事务
select spid 进程,STATUS 状态, 登录帐号=SUBSTRING(SUSER_SNAME(sid),1,30)
,用户机器名称=SUBSTRING(hostname,1,12)
,是否被锁住=convert(char(3),blocked)
,数据库名称=SUBSTRING(db_name(dbid),1,20),cmd 命令,waittype as 等待类型
,last_batch 最后批处理时间,open_tran 未提交事务的数量
from master.sys.sysprocesses
Where status='sleeping' and waittype=0x0000 and open_tran>0
二、查看锁定的语句等
select t1.resource_type [资源锁定类型],DB_NAME(resource_database_id) as 数据库名
,t1.resource_associated_entity_id 锁定对象,t1.request_mode as 等待者请求的锁定模式
,t1.request_session_id 等待者SID
,t2.wait_duration_ms 等待时间
,(select TEXT from sys.dm_exec_requests r cross apply
sys.dm_exec_sql_text(r.sql_handle) where r.session_id=t1.request_session_id) as 等待者要执行的SQL
,(select SUBSTRING(qt.text,r.statement_start_offset/2+1,
(case when r.statement_end_offset=-1 then DATALENGTH(qt.text) else r.statement_end_offset end -r.statement_start_offset)/2+1
)
from sys.dm_exec_requests r cross apply sys.dm_exec_sql_text(r.sql_handle)qt
where r.session_id=t1.request_session_id) 等待者正要执行的语句
,t2.blocking_session_id [锁定者SID]
,(select TEXT from sys.sysprocesses p cross apply
sys.dm_exec_sql_text(p.sql_handle)
where p.spid=t2.blocking_session_id
) 锁定者执行语句
from sys.dm_tran_locks t1,sys.dm_os_waiting_tasks t2
where t1.lock_owner_address=t2.resource_address
