    Description

      Create UDFS for these functions.

      CHR: convert n where n : [0, 256) into the ascii equivalent as a varchar. If n is less than 0 or greater than 255, return the empty string. If n is 0, return null.

      REPLACE: replace all substrings of 'str' that match 'search' with 'rep'.
      Example. SELECT REPLACE('Hack and Hue', 'H', 'BL');
      Equals 'BLack and BLue'"
