Invalid conversion between DATE column <str> and host variable
  <str>

  Explanation:  Only binary dates can be compared or assigned to
  or from DATE columns.

  User Action:  Use a date declaration for the host variable to be
  used with the date field:  in COBOL, use S9(11)V9(7) COMP; in
  PL/I, use CHAR(8) or BYTE_FIELD(8); in FORTRAN, use CHARACTER*8.
