MDA Tables: Why is the owner_name omitted in most of the MDA tables?

Hi all,

If you look at the MDA poster, you will find the object names, the database names and the like but not the owner_id or owner_name.  Let's pick on monOpenObjectActivity, one of the most heavily used mda tables

Having monOpenObjectActivity is great but what if I have two tables named the same in the same database with a different owner?  Such a scenario is not uncommon in a development system when having a separate database for each developer is not practical.

A row in monOpenObjectActivity could be mydb.john.table_a or mydb.jane.table_a.  While I do have the object id, there is no owner_name(DBID, OBJID) function, so I need to go into each individual database and query sysobjects.  What a hassle!  ASE already knows, or should know, which owner id the object belongs to so why need I have to create a dynamic query for each and every row in monOpenObjectActivity?  Sure, I could create a look up table but it wouldn't be able to handle temporary objects (e.g. #table) very well.

The following tables have Owner something in the column names:

1> select convert(varchar(30), object_name(id)) as "Object Name", convert(varchar(30), name) as "Column Name" from syscolumns where lower(name) like "%owner%"

2> go

Object Name                    Column Name

------------------------------ ------------------------------

monProcessObject               OwnerUserID

monCachedProcedures            OwnerUID

monCachedProcedures            OwnerName

monProcessProcedures           OwnerUID

monSpinlockActivity            OwnerPID

monSpinlockActivity            LastOwnerPID

monMemoryUsage                 PoolOwnerKPID

monProcessProcedures           OwnerName

monCachedObject                OwnerUserID

monCachedObject                OwnerName

sp_namecrack                   @owner

I think we need two functions:  owner_name(DBID, OBJID) and owner_id(DBID, OBJID)

We also need the OwnerID and preferrably OwnerName added to the appropriate MDA tables.

What do you think?

Hi Jason,

We did sneak in an object_owner_id() function in 15.5.

wonderful Bret, what about the name of the owner?  I'm assuming object_owner_id is querying the appropriate sysobjects?

did not find elegant approach, just some workarounds, which mostly already were mentioned in initial message

1) select user_name(object_owner_id(1)) refers only to the users in current database

so alternatively would be nice to have second argument for user_name

2) it is possible to create function like this

create function owner_name(@objid int, @dbid int = null)

returns longsysname



    declare @n longsysname

    declare @sql varchar(8000)

    set @objid = isnull(@objid,db_id())

    set @sql = 'select @n=name from ' + db_name(@dbid) + '..sysusers where uid=' + convert(varchar,object_owner_id(@objid, @dbid))

    execute (@sql)

    return @n


but this is actually what you said "create a dynamic query for each and every row"

3) if I correctly understand your idea about look up table, you meant to create look up table for object-to-user,.. suppose object_owner_id might bring some new life to this idea, just create look up table/view for sysusers

create view allsysusers


select db_id('pubs2') dbid , uid, name from pubs2..sysusers

union all

select db_id('pubs3') dbid , uid, name from pubs3..sysusers

select, o.ObjectName

from monOpenObjectActivity o

join allsysusers u on object_owner_id(o.ObjectID, o.DBID) = u.uid and o.DBID = u.dbid
