Sqlite: Disable value method for fundamentals

There is optionalValue which can handle a null value. ints and floats
can be initialize to zero but you cannot be sure that this value comes
from the database, is a empty value. So it's better to force
the use of optionalValue for ints and floats. In that case empty has
to be handled.
