IDBProperties (OLE DB)
SQL Server Native Client (SNAC) is not supported beyond SQL Server 2012. Avoid using SNAC in new development work, and plan to modify applications that currently use it. The Microsoft ODBC Driver for SQL Server provides native connectivity from Windows to Microsoft SQL Server and Microsoft Azure SQL Database.
The OLE DB standard specification allows providers to specify VT_EMPTY for DBPROPINFO::vValues. However, SQL Server Native Client OLE DB always returns VT_EMPTY when you call IDBProperties::GetPropertyInfo with DBPROPSET_ROWSETALL to retrieve rowset properties.
