Article

The ADORecordsetConstruction interface is used to construct an ADO Recordset object from an OLE DB Rowset object in a C/C++ application.

This interface supports the following properties:

Properties

Chapter	Read/Write. Gets/sets an OLE DB Chapter object from/on this ADO Recordset object.
RowPosition	Read/Write. Gets/sets an OLE DB RowPosition object from/on this ADO Recordset object.
Rowset	Read/Write. Gets/sets an OLE DB Rowset object from/on this ADO Recordset object.

Methods

None.

Events

None.

Remarks

Given an OLE DB Rowset object (pRowset), the construction of an ADO Recordset object (adoRs) amounts to the following three basic operations:

Create an ADO Recordset object:

Recordset20Ptr adoRs;
adoRs.CreateInstance(__uuidof(Recordset));

Query the IADORecordsetConstruction interface on the Recordset object:

adoRecordsetConstructionPtr adoRsConstruct=NULL;
adoRs->QueryInterface(__uuidof(ADORecordsetConstruction),
                     (void**)&adoRsConstruct);

Call the IADORecordsetConstruction::put_Rowset property method to set the OLE DB Rowset object on the ADO Recordset object:
```
IUnknown *pUnk=NULL;
pRowset->QueryInterface(IID_IUnknown, (void**)&pUnk);
adoRsConstruct->put_Rowset(pUnk);
```

The resultant adoRs object now represents the ADO Recordset object constructed from the OLE DB Rowset object.

You can also construct an ADO Recordset object from an OLE DB Chapter or RowPosition object.
