DAYS ( expression )
The argument must be either a:
v Date
v Timestamp
v Valid character representation of a date
The result of the function is a binary field. If the argument can be null, the result can be null. If the
argument is null, the result is null.
The result is one more than the number of days from January 1, 0001 to D, where D is the date that
would occur if the DATE function were applied to the argument.
