這有什麼，與你的首要問題，但作爲一個建議，你應該清理你的在將變量輸入到查詢之前發佈變量。 – 2010-09-29 17:29:58

標準SQL不允許您引用WHERE子句中的聚合列。您需要將trans_paid條件移至HAVING條款以使其工作。

變化

WHERE (o.order_status =7 or o.order_status = 4) 
    AND trans_paid IS NOT NULL 
    AND acct.is_wholesale =1 
    AND acct.acct_company LIKE '%".$_POST['company']."%' 
GROUP BY o.order_id

到

WHERE (o.order_status =7 or o.order_status = 4) 
    AND acct.is_wholesale =1 
    AND acct.acct_company LIKE '%".$_POST['company']."%' 
GROUP BY o.order_id 
HAVING trans_paid IS NOT NULL

您可以：

我的查詢（$ FROM_DATE和$ TO_DATE的格式是否正確）「在 'where子句' 未知列 'trans_paid'」在WHERE子句的SELECT原因中引用別名列。如果您想過濾它，您必須將其包裝在子查詢中。

要在Where子句中使用的別名必須在FROM子句中聲明...您只需重命名列而不實際重命名對象（如表）。

使用此查詢：

SELECT 
    o.order_id, 
    o.order_po_no, 
    o.order_ship_date, 
    acct.acct_company, 
    SUM(ROUND(i.item_qty * i.item_price, 2)) AS item_amount, 
    trans_paid 
    FROM orders AS o 
    LEFT JOIN 
    (SELECT SUM(trans_amount) AS trans_paid 
    FROM 
    WHERE trans_pending =0 
    AND trans_date >= '$from_date' 
    AND trans_date <= '$to_date' 
    ) temp 
    USING order_id 

    INNER JOIN accounts AS acct ON o.acct_id = acct.acct_id 
    INNER JOIN items AS i ON o.order_id = i.order_id 
    WHERE (o.order_status =7 or o.order_status = 4) 
     AND trans_paid IS NOT NULL 
     AND acct.is_wholesale =1 
     AND acct.acct_company LIKE '%".$_POST['company']."%' 
GROUP BY o.order_id
