Bookmarks

Bookmarks allow consumers to return quickly to a row. With bookmarks, consumers can access rows randomly based on the bookmark value. The bookmark column is column 0 in the rowset. The consumer sets the dwFlag field value of the binding structure to DBCOLUMNSINFO_ISBOOKMARK to indicate that the column is used as bookmark. The consumer also sets the rowset property DBPROP_BOOKMARKS to VARIANT_TRUE. This allows column 0 to be present in the rowset. The IRowsetLocate::GetRowsAt method is then used to fetch rows, starting with the row specified as an offset from a bookmark.
