Description: Multiple Results

A bitmask specifying whether the provider supports multiple results objects and what restrictions it places on these objects. A combination of zero or more of the following:

• DBPROPVAL_MR_SUPPORTED—The provider supports multiple results objects.
  
  
• DBPROPVAL_MR_CONCURRENT—More than one rowset created by the same multiple results object can exist concurrently. If this bit is not set, the consumer must release the current rowset before calling IMultipleResults::GetResult to get the next result.

If multiple results objects are not supported, DBPROPVAL_MR_NOTSUPPORTED is returned. For more information about multiple results, see "Multiple Results" in Chapter 3, "Commands."
