Doron,

I understand that you may not be able to change the notes table layout, but if you can I would suggest the following structure:

Notes.Id
Notes.Parent_Table
Notes.Parent_id
Notes.Note

With this kind of layout the where clause of your view would be

where notes.parent_table=?cParentTable and notes.parent_id=?parentid
