   LONG lSkip = 0    
) throw( );

Parameters

bookmark
[in] A bookmark marking the location from which you want to fetch data.

lSkip

Remarks

This method requires the optional interface IRowsetLocate, which might not be supported on all providers; if this is the case, the method returns E_NOINTERFACE. You must also set DBPROP_IRowsetLocate to VARIANT_TRUE and set DBPROP_CANFETCHBACKWARDS to VARIANT_TRUE before calling Open on the table or command containing the rowset.
