How Do I Use an Existing ADO Recordset?

  • Article

To mix OLE DB consumer templates and Active Data Objects, use ADO to open a recordset (corresponding to a rowset in the OLE DB consumer templates). Once you have a recordset, do the following to connect to an OLE DB rowset:

  1. Call QueryInterface for the IRecordset and IAccessor pointers.

    IRowset* lpRowset = NULL;
IAccessor* lpAccessor = NULL;
lpUnk->QueryInterface(IID_IRowset, (void**)&lpRowset);
lpUnk->QueryInterface(IID_IAccessor, (void**)&lpAccessor);

  2. Attach the accessor and rowset to their appropriate OLE DB consumer template classes.

    CRowset rs;
CAccessor accessor;

accessor.Attach(lpAccessor);
rs.Attach(lpRowset);
rs.SetAccessor(accessor);
