I dont want use all the values in my second program I need to pass empno and job only.Since your cursor gets all the columns (using the * is not a good way to code the cursor), that is what your other program will get when it calls pr_test procedure. You will have to FETCH all the columns in that other procedure and discard the ones you do not need.
Alternatively, change the code of cursor to select only the columns you would actually need.
