calling sp with datetime parameter from ole db

Hi folks,
I have a huge problem calling a stored proc with a datetime parameter using
ole db (CDynamicParameterAccessor). I used the sample from MSDN (HOWTO: Exec
ute Stored Procedure Using CDynamicParmeterAccesor) as a starting point and
modified the sp "sp_getStudent" so that it gets another parameter @.d datetim
e. But now I'm not able to execute this proc any more: rs.open() returns 0x8
0040e21 (DB_E_ERRORSOCCURRED). What's wrong?!?
Kind regards
Thomas
P.S. Any other kind of third parameter (int, float, ...) works well but date
time (smalldatetime) doesn'tHi Thomas
Your errror seems to be:
DB_E_DATAFIELD_OVERFLOW 80040E21 OLE DB Specific:
The field is too small to accept the amount of data you attempted to add.
Try inserting or pasting less data.
Check the values of the parameters you are passing and (possibly) if you are
mixing the values/parameters up (it is better to add the parameters in the
order in which they are declared!)

is smalldatetime, I'd check the date value being put in and make sure
it's a valid smalldatetime (which is quite different than datetime).
valid smalldatetime values are Jan 1, 1900 to June 6, 2079.

thank's for the info - the problem is that I do not make any parameter-bindi
ng on my own, I just call
rs.Create(session, "exec sp_getstudent ?, ? out, ? out");
rs.Prepare();
rs.BindParameters(&rs.m_hParameterAccessor, rs.m_spCommand, &pDummy);
the same way as I do without the datetime parameter, but the next call to
rs.Open(NULL, NULL, false);
returns the error stated below...
Kind regards

I assume that you are setting the first parameter as in the example code?
Does SQL profiler show anything?

being passed to sql server.
Since you're getting the parameter values from the UI, I even more
confident that you're getting an invalid smalldatetime value.
