Syntax options:

       MAXVALUE TINYINT
       MAXVALUE SMALLINT
       MAXVALUE INTEGER
       MAXVALUE BIGINT

    SQL allows the keyword TINYINT, SMALLINT, INTEGER and BIGINT
    to follow MAXVALUE instead of a numeric value. This allows easy
    range setting for sequences used with these data types. The value
    supplied will be the largest positive value that can be assigned
    to this data type.
