OpenRowset	Opens and returns a rowset that includes all rows from a single base table or index. (Not in ATLDB.H)

Remarks

The IOpenRowset interface is mandatory for a session object. It opens and returns a rowset that includes all rows from a single base table or index.

IOpenRowsetImpl::CreateRowset

Creates a rowset object. Not called directly by user. See IOpenRowset::OpenRowset in the OLE DB Programmer's Reference.

Syntax

template template <class RowsetClass>
HRESULT CreateRowset(IUnknown* pUnkOuter,
   DBID* pTableID,
   DBID* pIndexID,
   REFIID riid,
   ULONG cPropertySets,
   DBPROPSET rgPropertySets[],
   IUnknown** ppRowset,
   RowsetClass*& pRowsetObj);

Parameters

RowsetClass
A template class member representing the user's rowset class. Usually generated by the wizard.

pRowsetObj
[out] A pointer to a rowset object. Typically this parameter is not used, but it can be used if you must perform more work on the rowset before passing it to a COM object. The lifetime of pRowsetObj is bound by ppRowset.

For other parameters, see IOpenRowset::OpenRowset in the OLE DB Programmer's Reference.
