Here I have a table locked by another process, so I cannot access it. I try writing a T-SQL to find the lucked or blocked process id and kill it. But seems that the query result column [A.blocked ] do not show the ture situation(always return 0). In this way I cannot find the lucked spid.

select   B.name,   A.cmd,   A.spid,A.blocked   from   master..sysprocesses  A   
join master..sysdatabases B on A.dbid = B.dbid
where B.name = DB_NAME()



Any friends have better idea? Go a step further, is it possible to find the lucked table?
Thanks!:-P

Don't use sysprocesses, it's deprecated, included only for backward comparability and will be removed in a future version.
Use sys.dm_exec_requests and/or sys_dm_tran_locks.

The way to 'unlock' a table is to kill the connection holding the lock, or wait for that connection to finish what it's doing and let SQL release the locks.

You can also check the "processes" section of the activity monitor. Right click on the server in the object explorer and choose "activity monitor".
