查询锁事务及语句

if exists(select * from master.sys.sysprocesses where spid in (select blocked from master.sys.sysprocesses))

begin

---确定进程被锁住的其他资源

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

--列出锁住别人（在别的进程中blocked字段中出现的值）但自己未被锁住(blocked=0)

Where spid in (select blocked from master.sys.sysprocesses) and blocked=0

end

else 

begin

select '没有被锁住的进程'

end 

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
