Thanks George for the links. I went through the examples and have observed that in all the cases, a corresponding C structure is known for the user defined type at compile time and hence it has been hardcoded. This structure is then used to allocate memory in the OCIDefineByPos and OCIDefineObject calls so as to receive a row of data during the OCIStmtFetch call.
However my problem is that I donot know the structure of the type at compile time. I am making a general purpose data access mechanism and hence cannot hard-code any C structures in my code. I would rather know the structure of the object at runtime and then fetch the object. Looking forward to some more help in this regard.
