SQL is strictly typed, there should be no implicit conversions between numeric types. The only possible exception is conversion of a lossless conversion of a numeric literal, e.g.: float_val = 1.1 -- implicitly convert decimal constant 1.1 to float > 4) Implicit casting is prohibited, except as described above. > > > I think that the rules for implicit casting when assigning value > of numeric type must be the same as in C. > -- Konstantin Osipov, Moscow, Russia https://scylladb.com
