Question

DELIMITER $$

CREATE FUNCTION fixString(input varchar) RETURNS varchar
B         


        

Answer 1

You're using VARCHAR, so you have to indicate a max size:

DELIMITER $$

CREATE FUNCTION fixString(input varchar(15)) RETURNS varchar(15)
BEGIN
  declare output varchar(15);
  SET output = REPLACE(input,'ö','oe');
  RETURN output;
END $$

DELIMITER ;
