My fancy schmancy lock status query for ASE

Originally posted as an answer in https://answers.sap.com/questions/13420793/locking-on-tablestable-lock.html

This is my fancy schmancy query to show lock statuses, including blocked lock requests.  Note that blocked lock requests aren’t shown by sp_lock, although sp_who will show the process requesting the lock as blocked:

set nocount on
select p.spid, p.status, p.hostname, hostpid=p.hostprocess, p.program_name, p.cmd, BlockedOnSpid=p.blocked,
       object=l.DBName+".."+object_name(l.ObjectID,l.DBID),
       l.LockID, l.LockState, l.LockType, l.LockLevel, WaitSecs=l.WaitTime, l.BlockedState, BlockedByLockID=l.BlockedBy, cnt=count(*)
into #tmp_cnt
from master..sysprocesses p, master..monLocks l
where p.spid=l.SPID and p.spid!=@@spid
group by p.spid, p.status, p.hostname, p.hostprocess, p.program_name, p.cmd, p.blocked,
         l.DBName+".."+object_name(l.ObjectID,l.DBID),
         l.LockID, l.LockState, l.LockType, l.LockLevel, l.WaitTime, l.BlockedState, l.BlockedBy


exec sp_autoformat @fulltabname = "#tmp_cnt",
                   @selectlist  = "spid, status, hostname, hostpid, program_name, cmd, BlockedOnSpid, object,LockID, LockState, LockType, LockLevel, WaitSecs, BlockedState, BlockedByLockID, cnt",
                   @orderby     = "order by spid, status, hostname, hostpid, program_name, cmd, BlockedOnSpid, object, LockID, LockState, LockType, LockLevel"
drop table #tmp_cnt

It produces output like (santized for privacy reasons):

spid status     hostname hostpid program_name   cmd               BlockedOnSpid object                LockID LockState  LockType         LockLevel WaitSecs BlockedState BlockedByLockID cnt
