How can I modify the attribute value of property or field in ADO?

hi all:

I think up a substitute way when the recordset-A that created by store procedure in ORACLE can't updatable:

if I use ADO-command object to set a sql statement for commandtext ,

I can get a recordset-B that can be updatebatch.

then I modify the attributes of the recordset-A through the value of the

attributes of the recordset-B.

I think that I will successful updatebatch the recordset-A if Its attributes

can be modify.

But:

in VC++6&ADO:

//the code is:

FieldPtr pField2 = updRecordset->GetFields()->GetItem(CComVariant(i));

//operation:

pField2->GetProperties()->GetItem(CComVariant(j))->PutValue(val1);

//or

pField2->GetProperties()->GetItem(CComVariant(j))-
>PutAttributes(adPropWrite);

//to modify the attributes of recordset-B,

but It is appear a error message:"Operation is not allowed in this context."

so why and how can I do?

best regards.
