Supported OLE DB Properties
Important
This feature will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Instead, write a fully functional OLE DB provider using the native OLE DB interfaces.

DBPROP_COLUMNRESTRICT |
OSPStatusRW When an OSP contains a read-only rowset (that is, getRWStatus() returns OSP_READONLY for all rows and columns), Msdaosp.dll sets properties DBPROP_ROWRESTRICT and DBPROP_COLUMNRESTRICT to VARIANT_TRUE. This reflects the possibility that the OSP might still allow new rows to be added, and these new rows might be updatable. If a new, updatable row is added, columns might have mixed write status. |

DBPROP_ROWSET_ASYNCH |
DBPROPVAL_ASYNCH_SEQUENTIALPOPULATION Default value is (DBPROPVAL_ASYNCH_INITIALIZE | DBPROPVAL_ASYNCH_SEQUENTIALPOPULATION | DBPROPVAL_ASYNCH_RANDOMPOPULATION) Supported as READWRITE, but population of the rowset is determined by the underlying OSP by using the OLEDBSimpleProvider::isAsync method. Unless the underlying OSP is asynchronous, setting property DBPROP_ROWSET_ASYNCH will have no effect. Msdaosp.dll will not return until the rowset is populated. |
