How to get Standard SQL out from Query Object in AOT?

Hello,

I'm trting to get SQL out of Query Object made in AOT.

Tried this code BUT it only returns the first SQL clause not all ones combined together.

I think that dataSourceNo(1) <= numer one here restrictes getting all SQL code.

Any ideas, how to do it?

Query query;    

QueryBuildDataSource qbd;    

QueryBuildRange qbr;    

QueryRun qr;    

;

query = new Query(queryStr(WorkInstructionsQry));    

qbd = query.addDataSource(TableNum(ProdTable));    

qbr = qbd.addRange(FieldNum(ProdTable, ProdId));    

 qbr.value("PRD_00000062");    

 qr = new QueryRun(query);    

 info(qr.query().dataSourceNo(1).toString());

Br
