Sie werden nicht in der Lage Beschreibung und Modell Spalte Wert zuzugreifen, weil Ihr nicht Lust Spaltennamen in der Abfrage angeben, so dass, wenn Sie versuchen, Abfrageergebnis zugreifen in PHP erhalten Sie Notice Error wie:

Hinweis: Undefinierter Index: Beschreibung, Hinweis: Undefinierter Index: Modell.

Diese Abfrage

$sql = "select description,model,t.itemcode as itemcode ,sum(t.qty) as qty 
    from ( 
    select description,model,itemcode,qty from barcode as bc INNER JOIN allinventory_tb as ait on bc.itemcode = ait.in_code 
    union all 
    select description,model,itemcode,qty from adjustment_tb as adt INNER JOIN allinventory_tb as ait1 on adt.itemcode = ait1.in_code where adjustment_tb.status='APPROVED' 
    union all 
    select description,model,itemcode,(qty * -1) from soldout_pd as slp INNER JOIN allinventory_tb as ait2 on slp.itemcode = ait2.in_code) as t
