Provides a default implementation for the row handle, which is used in the IRowsetImpl class.

class CSimpleRow

Header: atldb.h

A row handle is logically a unique tag for a result row. IRowsetImpl creates a new CSimpleRow for every row requested in IRowsetImpl::GetNextRows. CSimpleRow can also be replaced with your own implementation of the row handle, as it is a default template argument to IRowsetImpl. The only requirement to replacing this class is to have the replacement class provide a constructor that accepts a single parameter of type LONG.

Adds a reference count to an existing row handle in a thread-safe manner.

DWORD AddRefRow();

Compares two rows to see if they refer to the same row instance.

HRESULT Compare(CSimpleRow* pRow);

pRow
A pointer to a CSimpleRow object.

An HRESULT value, usually S_OK, indicating the two rows are the same row instance, or S_FALSE, indicating the two rows are different. See IRowsetIdentity::IsSameRow in the OLE DB Programmer's Reference for other possible return values.

The constructor.

CSimpleRow(DBCOUNTITEM iRowsetCur);

iRowsetCur
[in] Index to the current rowset.

Sets m_iRowset to iRowsetCur.

Releases rows in a thread-safe manner.

DWORD ReleaseRow();

Reference count to an existing row handle.

DWORD m_dwRef;

Index to the rowset representing the cursor.

KeyType m_iRowset;
