Provides a default implementation for the row handle, which is used in the IRowsetImpl class.
Syntax
class CSimpleRow
Members
Methods
| AddRefRow | Adds a reference count to an existing row handle. |
| Compare | Compares two rows to see if they refer to the same row instance. |
| CSimpleRow | The constructor. |
| ReleaseRow | Releases rows. |
Data Members
| m_dwRef | Reference count to an existing row handle. |
| m_iRowset | An index to the rowset representing the cursor. |
Remarks
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.
