hi 

I have a AOT query with 1 datasource. I want to change the query range if projid='' and serviceId !''.

In the datasource init() I have this code, but I dont get the required result.

public void init()
{
    QueryBuildDataSource        qbds;    
    QueryRun                    qr;
    
    
    super();
    
    qbds = this.query().dataSourceName('ServiceInvoiceLine_2');
    qr  = new QueryRun(this.query());
    
    while(qr.next())
    {      
        if(ServiceInvoiceLine_2.Projid != '' && ServiceInvoiceLine_2.ServiceOrderid == '')
        {
            qbdsTimeLine.addRange(fieldNum(ServiceInvoiceLine, ServiceOrderid)).value('!""');
            qbdsTimeLine.addRange(fieldNum(ServiceInvoiceLine, Projid)).value("");
            qbdsTimeLine.addRange(fieldNum(ServiceInvoiceLine, jobid)).value('!=""');
        }
    }
}

    You mentioned a data source, so I'll assume it's init() method of a form datasource. Please confirm whether it's the case and don't forget to mention such crucial things next time.

    Your code looks very strange; I suspect you don't understand what it does, so let me explain it to you.

    You take the datasource query, fetch all records and if the record currently loaded in the form (not the ones you get from the query) has a non-empty ProjId and and empty ServiceOrderId, you add three ranges.

    Therefore is the query return 500 records, you add 1500 (500*3) ranges. That's not very useful.

    Also, whether the ranges will be added or not depends on which record is currently selected. It doesn't depend in any way on records returned by the query. You fetch all records from database but you ignore them completely. If it should depend only on the active record, you can throw away all the code executing the query.

    I think we shouldn't spend more time with your current code. You should rather tell us what exactly you're trying to achieve and we'll help you design something better.

    Use this qbrCustRef.value(SysQuery::valueNotEmptyString());

    What is "qdbsTimeLine"? Where is it initialized?
