Oh, Cool, It is great solution. I'm sorry in explanation having been lacking.
Sorry, my explanation is insufficient...SQL_CURSOR_KEYSET_DRIVEN
does not become effective together with DECLARE/FETCH options.
It can be used as the option of UPDATE cursor.
Correctly, it should have made it TODO to use with it.
Anyway, I'm sorry confused the user.
