Query object not working as expected? - axapta

Question

This code should be able to run on any AX system (change item & warehouse). The issue is that CustInvoiceJour is not being returned sometimes. What is odd, is if I just do a "select custInvoiceJour" with the same relations, it DOES find it? How is this possible?
static void Job59(Args _args)
{
CustInvoiceTrans custInvoiceTrans;
CustInvoiceJour custInvoiceJour;
InventTable inventTable;
QueryBuildRange rangeItem;
Query query;
QueryBuildDataSource qbds1;
QueryBuildDataSource qbds2;
QueryBuildDataSource qbds3;
QueryRun qr;
;
query = new Query();
qbds1 = query.addDataSource(tablenum(CustInvoiceTrans));
qbds2 = qbds1.addDataSource(tablenum(CustInvoiceJour));
qbds2.relations(true);
qbds2.addRange(fieldnum(CustInvoiceJour, SalesType)).value('!' + enum2str(SalesType::ReturnItem));
rangeItem = qbds1.addRange(fieldnum(CustInvoiceTrans, ItemId));
qbds1.addRange(fieldnum(CustInvoiceTrans, InvoiceDate)).value(queryRange(#'8/1/2011', #'8/31/2011'));
qbds2.orderMode(OrderMode::OrderBy);
qbds2.addOrderByField(fieldnum(CustInvoiceJour, DlvCountryRegionId));
qbds2.addOrderByField(fieldnum(CustInvoiceJour, DlvState));
qbds3 = qbds1.addDataSource(tablenum(InventDim));
qbds3.relations(true);
qbds3.joinMode(JoinMode::ExistsJoin);
qbds3.addRange(fieldnum(InventDim, InventLocationId)).value(SysQuery::value('FG'));
select firstonly inventTable
where inventTable.ItemId == '44831';
info (strfmt("%1", inventTable.ItemId));
rangeItem.value(inventTable.ItemId);
qr = new QueryRun(query);
while (qr.next())
{
custInvoiceTrans = qr.get(tablenum(CustInvoiceTrans));
custInvoiceJour = qr.get(tablenum(CustInvoiceJour));
if (!custInvoiceJour)
{
info ("Not found");
select firstonly custInvoiceJour
where custInvoiceJour.SalesId == custInvoiceTrans.SalesId &&
custInvoiceJour.InvoiceId == custInvoiceTrans.InvoiceId &&
custInvoiceJour.InvoiceDate == custInvoiceTrans.InvoiceDate &&
custInvoiceJour.numberSequenceGroup == custInvoiceTrans.numberSequenceGroup;
if (custInvoiceJour)
info("Found it");
}
}
}
The debugger shows these as the queries:
NAME:
qbds1
VALUE:
SELECT * FROM CustInvoiceTrans ORDER BY CustInvoiceJour.DlvCountryRegionId ASC, CustInvoiceJour.DlvState ASC WHERE ((ItemId = N'44831')) AND ((InvoiceDate>={ts '2011-08-01 00:00:00.000'} AND InvoiceDate<={ts '2011-08-31 00:00:00.000'})) EXISTS JOIN * FROM InventDim WHERE CustInvoiceTrans.InventDimId = InventDim.inventDimId AND ((InventLocationId = N'FG'))
NAME:
qbds2
VALUE:
SELECT * FROM CustInvoiceJour WHERE CustInvoiceTrans.SalesId = CustInvoiceJour.SalesId AND CustInvoiceTrans.InvoiceId = CustInvoiceJour.InvoiceId AND CustInvoiceTrans.InvoiceDate = CustInvoiceJour.InvoiceDate AND CustInvoiceTrans.numberSequenceGroup = CustInvoiceJour.numberSequenceGroup AND ((NOT (SalesType = 4)))
NAME:
qbds3
VALUE:
SELECT * FROM InventDim WHERE CustInvoiceTrans.InventDimId = InventDim.inventDimId AND ((InventLocationId = N'FG'))

Answer 1

Your qbds1 value doesn't show JOIN * FROM CustInvoiceJour WHERE ... (joined qbds2).
Add qbds2.fetchMode(QueryFetchMode::One2One); to your code and everything should be alright.
P.S. I would suggest to do it the other way round: CustInvoiceJour in qbds1, and CustInvoiceTrans in qbds2 (with default fetchMode), then you wouldn't have this problem at all.
