Re: Puzzled: CURSOR in Package

Thanks, Conner , for your input.
[Quoted] I understand but I still can't help thinking: The exact SAME benefits you indicated.... can it not be achieved by simply put the WHOLE cursor declaration AND definition in the pkg spec as opposed just the cursor header in the pkg spec ?

I mean I can just modify the SQL in the spec and recompile and nothing else is affected, right ?
So this goes back to my original question. ie Putting the cursor in spec, that's good and well. But what I am wondering is why the SELECT in the body.
