Oracle Objects - Using Parameter Arrays

I am using Oracle Objects to access an Oracle8 database from a Windows98 machine. As I am updating across a network I want to implement Parameter Arrays
to try and tune the performance. However when I try and create an OParamArray using OParameterCollection::AddTable() command it doesn't seem to succeed.

Actual Code used :


OParameterCollection params = m_Odb.GetParameters();
OParamArray arrCurrValues = params.AddTable("VALUEARRAY", OPARAMETER_OUTVAR, OTYPE_NUMBER, 50);




Does anyone know why this isn't working for me ?

cheers,
des.
