Outer joins with where condition x++ - axapta

Question

I am trying to write a query that retrieves an item based on ItemId or item barcode.
This is using x++, Dynamics AX 2012 R2
select firstOnly * from inventTable
where (inventTable.ItemId == _upc || inventItemBarcode.itemBarCode == _upc)
outer join inventItemBarcode
where inventItemBarcode.itemId == inventTable.ItemId;
When this is translated into sql it comes out as...
FROM INVENTTABLE T1 LEFT
OUTER
JOIN INVENTITEMBARCODE T2 ON (((T2.PARTITION=?)
AND (T2.DATAAREAID=?))
AND (T1.ITEMID=T2.ITEMID))
WHERE (((T1.PARTITION=?)
AND (T1.DATAAREAID=?))
AND (T1.ITEMID=?))
You can see that is is totally omitting the OR condition in the last line.
I tried writing the query like this
select firstOnly * from inventTable
outer join inventItemBarcode
where
//join
inventItemBarcode.itemId == inventTable.ItemId
//ilc
&& (inventTable.ItemId == _upc
|| inventItemBarcode.itemBarCode == _upc);
But it puts the OR condition in the outer join ON and then returns me the first row in the InventTable.
Does anyone know how to make this work in X++?

If using AX 2012 you will have to use Query and QueryRun instead, then add your or-expression as a query expression using addQueryFilter.
static void Job117(Args _args)
{
str search = "5705050765989";
QueryRun qr = new QueryRun(new Query());
QueryBuildDataSource ds1 = qr.query().addDataSource(tableNum(InventTable));
QueryBuildDataSource ds2 = ds1.addDataSource(tableNum(InventItemBarcode));
str qstr1 = '((%1.%2 == "%5") || (%3.%4 == "%5"))';
str qstr2 = strFmt(qstr1, ds1.name(), fieldStr(InventTable,ItemId),
ds2.name(), fieldStr(InventItemBarcode,ItemBarCode),
queryValue(search));
qr.query().addQueryFilter(ds1, fieldStr(InventTable,ItemId)).value(qstr2);
ds2.joinMode(JoinMode::OuterJoin);
ds2.relations(true);
info(qstr2);
info(ds1.toString());
while (qr.next())
info(strFmt("%1", qr.getNo(1).RecId));
}
In prior AX versions you can make a view, then query the view using a query expressions by using the addRange method.
