Yes select into throws too_many_rows if there's more than one that matches the where clause. That's by design.
Maybe you want to use a for loop?

You don't know how to write a for loop?
Go read a book on PL/SQL or go on a training course.

If you do know how to write a for loop then you need to be more specific as to what the actual problem is.

Well I've no idea what you actually want that procedure to do.
It's hard to work out what someone wanted some code to do when the only thing you've got to work with is some code that doesn't do what they wanted.

Explain in words what you want the code to do.
