Description: Open Rowset Support
A bitmask describing support for opening objects through IOpenRowset.
- DBPROPVAL_ORS_TABLEThe provider supports opening tables through IOpenRowset (true for all providers).
- DBPROPVAL_ORS_INDEXThe provider supports specifying an index through IOpenRowset.
- DBPROPVAL_ORS_INTEGRATEDINDEXThe provider supports specifying both a table and an index in the same call to IOpenRowset::OpenRowset in order to open the rowset using the specified index.
- DBPROPVAL_ORS_STOREDPROCThe provider supports opening a rowset over stored procedures by specifying the stored procedure name in TableID. (For more information about TableID, see "Rowset Creation Example" in Chapter 4: Rowsets.)
- DBPROPVAL_ORS_HISTOGRAMThe provider supports opening a histogram rowset through the IOpenRowset::OpenRowset method. Providers supporting histograms should set this bit, as well as DBPROPVAL_TS_HISTOGRAM, in the DBPROP_TABLESTATISTICS property.
