How to find the nth record using the query(qr.addPageRange(postion,postion))

Hi All,

Below is the example of how to find the nth record position using query

static void nthrecordPos(Args _args)
{  
    Query                   q;
    QueryBuildDataSource    qbds;
    QueryRun                qr;
    PurchTable              purchTable;
   
    q = new Query();
    qbds= q.addDataSource(tableNum(PurchTable));
    qbds.addOrderByField(fieldNum(PurchTable, PurchId));
   
    qr = new QueryRun(q);
    qr.literals(true);
    qr.enablePositionPaging(true);
    qr.addPageRange(10,12);
   
    while ( qr.next() )
    {
        purchTable = qr.get(tablenum(PurchTable));
        info(strfmt("%1", purchTable.RecId));
    }
}

Let say in the purchTable having 100 records, wanted to find the 10 to12 th record, by using the "qr.addPageRange(10,12)", it fetches on the 10th, 11th and 12th records.
