利用 tsqlca_index 对dbio进行索引，在 vr.cpp里有例子。 
 
    tsqlca_index idx; 
 
    idx.build(data); 
 
    int search_rid,int_vid,rec_int_vid; 
    int keep_pos; 
    wchar_t * wval; 
 
    for(id=0;id<*dbio_attr.mrowcount;id ) 
    { 
      dbio_attr.getres(0,attr_vid); 
 
      if(!idx.search_first(attr_vid,&search_rid,&keep_pos)) 
      { 
        dbio_attr.next(); 
        continue; 
      }; 
 
      data->go_row(search_rid); 
      sprintf(col_name,"%s",dbio_attr.getres(1)); 
      if(data->getfieldid(col_name,&fid)) 
      { 
        while(1) 
        { 
          data->setvalue(fid,dbio_attr.getres(2)); 
 
          if(!data->next()) break; 
          if(w_strcmp(data->getaddr(0),attr_vid)!=0) 
            break; 
        }; 
      }; 
 
      dbio_attr.next(); 
    };
