PLS-00394: Wrong number of values in the INTO list of a fetch statement

Question

This is my attempt in creating a cursor in a stored procedure

   --Second Stored Procedure--
 CREATE OR REPLACE PROCEDURE sp_GetDiscountedRate (DiscountCode IN           


        

Answer 1

You have

12 columns in your cursor's SELECT part

but

11 columns in FETCH statement part

, i observe

CASE U.MilitaryDiscountCode WHEN DiscountCode THEN   
  Percentage*R.ReservationCost 
  ELSE R.ReservationCost END "REVISED_RESERVATION_COST"

part is missing in FETCH( or should be omitted in the SELECT part ).

It also represents a column, and it spoils 1-1 correspondence, which yields that error.
