The problem with the table DBC.AccessRights is that the data is not something easily readable. Many of the columns use a 4-byte IDs.
By joining a couple of tables to the DBC.AccessRights table, the information brought back is more meaningful. Also by adding a couple of predicates in a where clause will help isolate this information to the desired rights on a user, database, or what ever is being searched for.
sel UI.DatabaseNameI as "UserName", DI.DatabaseNameI as "DatabaseName", TI.TVMNameI as "ObjectName", TI.TableKind as "ObjectType", AR.FieldId, AR.AccessRight, AR.WithGrant, GI.DatabaseNameI as "GrantorName", AR.AllnessFlag, CI.DatabaseNameI as "CreatorName", AR.CreateTimeStamp, AR.LastAccessTimeStamp, AR.AccessCount from DBC.AccessRights AR inner join dbc.dbase UI on AR.UserId = UI.DATABASEID inner join dbc.dbase DI on AR.DatabaseId = DI.DATABASEID inner join dbc.dbase GI on AR.GrantorID = GI.DATABASEID inner join dbc.dbase CI on AR.CreateUID = CI.DATABASEID inner join dbc.tvm TI on AR.TVMId = TI.TVMId order by 2;
