The following select worked on FB 1.5.5, however on FB 2.1.1 it raises exception "Unsupported field type specified in BETWEEN predicate", but A.Arrival and S.Arrival are timestamp fields:

Select A.ID From Cars A
Where
 A.Situation = 'A' and
 (
   Cast(A.Arrival as Date) between '01.10.2008' and '30.10.2008'
 or
   (Select Min(Cast(S.Arrival as Date)) From History S
    Where S.Car_ID = A.ID) between '01.10.2008' and '30.10.2008';
 );

Why this error?
