How to create Query in AX 2012 through X ++ code

With the following job we can create and execute the query : 

Static void Querytest(Args _Args)

{

    Query query;

    QueryBuildDataSource queryBuildDataSource;

    QueryBuildDataSource queryBuildDataSource1;

    QueryBuildRange queryBuildRange;

    QueryRun  queryRun;

    CustTable custTable;

    DirPartyTable DirPartyTable;

    ;

    query=new query();      //Initialize Query

    queryBuildDataSource=query.addDataSource(tableNum(CustTable));   //Add Query

    queryBuildDataSource.addSortField(fieldNum(custTable,AccountNum),SortOrder::Descending); //Add sorting

    queryBuildRange=queryBuildDataSource.addRange(fieldNum(CustTable,AccountNum)); // Add Range

    queryBuildRange.value(queryValue('11')+('*')); // Add Query Value

    queryBuildRange=queryBuildDataSource.addRange(FieldNum(CustTable,AccountNum));

    queryBuildRange.value(queryValue('22')+('*'));

    

    //queryBuildDataSource1=queryBuildDataSource.addDataSource(tableNum(CustTrans)); //Add other Data Source for Joining

    //queryBuildDataSource1.relations(true);// Enable Relation

    // queryBuildDataSource1.joinMode(JoinMode::InnerJoin);//Define Join Mode

    

    queryRun= new QueryRun(query);   //Pass query to run it

    while(queryRun.next())

    {

        custTable=queryRun.get(tableNum(CustTable));

        print(strFmt("Customer Name, Account num and Currency are  %1 , %2 and %3",DirPartyTable::findRec(CustTable.Party).Name,CustTable.AccountNum,CustTable.Currency));

        pause;

    }

}
