hi，我在类中添加如下方法，但是query没有起到效果，请问是什么回事？多谢

public void createCalcData()
{
    Query                       query;
    QueryBuildDataSource        queryBuildDataSource;
    QueryRun                    queryRun;
    QueryBuildRange     queryBuildRange;

    PurchTable  purchTable2;
    PurchLine   purchline;

    ;

    query = new Query();
    queryBuildDataSource = query.addDataSource(tablenum(PurchTable));
    //queryBuildDataSource.addRange(fieldnum(PurchTable, PurchId)).value(SysQuery::value(_purchId));
    queryBuildDataSource.addRange(fieldnum(PurchTable, PurchId)).value("*7");  

    queryRun = new QueryRun(query);

    while (queryRun.next())
    {
            purchTable2 = queryRun.get(tablenum(PurchTable));
            while select purchTable2
            {
                i++;
                //info(purchTable2.PurchId);
            }
            ii++;

   }

    info(int2str(i));
    info(int2str(ii));

}

   }

谢谢！

但是这样不是我需要的结果，这只是偱环出来的结果

我需要的是过滤后的表

请问怎么写呀！
