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?
