Adding a value to a 'datetime' column caused overflow.

Hi,
When I use dateadd function to a table containing around 10000 values,
it gave the following msg. Adding a value to a 'datetime' column caused
overflow. What does it mean?
Thanks,
Mike
You are exceeding the valid datetime range differs if you use datetime
or smalldateimte, which command did you use ? could you please post the
commandtext you are using ? What is the datatype of you are doing the
dateadd operation.

I am using float type date to convert to a datetime. Please see the
following codes.
select dateadd(dd, Def_Date, '1/1/1960') from one;
Thanks,
Mike
