Join Two Tables at Run Time

How to join Two tables at RunTime, without using Datasource


static void QueryJoin2Tables(Args _agrs)
{
AxTestTable1 AxTestTable1;  // Table 1
AxTestTable2 AxTestTable2;  // another table which you want to join with table 1
Query q;
QueryBuildDataSource qbdAxTestTable1, qbdAxTestTable2;  // objects for both tables
QueryBuildRange qbr;
QueryRun qr;
;

        q = new Query(); //to make a new query

qbdAxTeatTable2 = q.addDataSource(tablenum(AxTestTable2)); // To Add table to query

        qbdAxTesttable2.addRange(fieldnum(AxTestTable2,RollNo)).value("2");

         qbdAxTeatTable1 = qbdAxTestTable2.adddataSource(tablenum(AxTestTable));

       qbdAxTesttable1.addlink(fieldnum(AXTestTable2,RollNo),fieldnum(AxTestTable,Rollno));

       qbdAxTestTable.joinMode(joinMode::InnerJoin);
    qr = new QueryRun(q); // to fetch records from query
while(qr.next())
{
AxTestTable1 = qr.get(tablenum(AxTestTable));
info(AxtestTable.RollNo);
}
}
