Does the Ole Db rowset support IGetRow interface?

Question

When I try to call QueryInterface() on a rowset object for interface IGetRow, it just return a E_NOINTERFACE.

Does the Ole Db rowset support IGetRow interface?

My connection string is:

Provider=SQLOLEDB;User ID=sa;password=111111;Data Source=Percy_pc;initial catalog=RHGame

The code getting IGetRow interface is:

		IGetRow* get_row;
		hr=row_set->QueryInterface(IID_IGetRow,(void**)&get_row);

Hi Percy,

Using the IGetRow interface to get a row object or URL for a row in a rowset, we have two methods:

IGetRow::GetURLFromHROW

IGetRow::GetRowFromHROW

Please refer to these references for how to using IGetRow interface in OLEDB:

I used Accessor instead of IGetRow to acheive the goal. Thanks.
