Hi Friends,

I am running into problem. Which appears it's query filter issue.

I have a form, let user put in start/end date to query vendtable and vendtrans tables.

In form init() method, I initialize the start/end date for last month, then, user can change the date to whenever they want.

Problem I had is, whenever the date user change to, it always keep the last month data plus the data within date range user just put in.

I tried to clean the filter when button clicked, but, it doesn't work.

Any help is appreciated.

Here is my code:

This is from vendtable datasource executequery() method:

------------------------------

//filter on VendTrans table

diversifiedVendTransQBR2 = this.query().dataSourceTable(TableNum(VendTrans)).addRange(fieldNum(VendTrans, TransDate));

diversifiedVendTransQBR2.value(SysQuery::range(StartDate.dateValue(), EndDate.dateValue()));




This is from FORM init():




public void init()



{



super();



 StartDate.dateValue(prevMth(systemdateget()));



 EndDate.dateValue(systemdateget());



}




This is from button click method:




void clicked()
{
    VendTable_ds.removeFilter();
    VendTrans_ds.removeFilter();
    VendTable_ds.refresh();



    VendTable_ds.executeQuery();



    super();
}

RE: Query filter cache

Unfortunately you didn't mention where you call the section "//filter on VendTrans table", but I'll assume it's in executeQuery(). Your code there always add a range, therefore if get executed ten times, you create ten ranges for the same field (with the same of different values). That's clearly wrong.

Removing the range first (as shown by Rustem) is one possible way.

Reusing the same range is the other. You can call addRange() in init() and storing the range in an instance variable or you can utilize SysQuery::findOrCreateRange().

You can pass a value to range on button click method or on modified on start date and end date . I don't know business requirement behind initializing dates in init method.

qbrCreatedDateTime.value(SysQuery::range(FromDate.dateValue(),ToDate.dateValue());

Hi Ganriver,

In executeQuery() method add the following line of code

this.query().dataSourceTable(TableNum(VendTrans)).clearRange(fieldNum(VendTrans, TransDate));

diversifiedVendTransQBR2 = this.query().dataSourceTable(TableNum(VendTrans)).addRange(fieldNum(VendTrans, TransDate));

diversifiedVendTransQBR2.value(SysQuery::range(StartDate.dateValue(), EndDate.dateValue()));

super();
