我正试图从订单查看订单.在我看来,我确实有一些行具有完全相同的值,但我想在orderid上对这些值进行分组,并获取该订单数量的总和.

我的观点结果如下:

 Order_id   Customer_id   Article_id   Delivery_date   Quantity
 ---------------------------------------------------------------------------
 PR10.001   11            20.001a      17-04-2013      1
 PR10.001   11            20.001a      17-04-2013      1
 PR10.001   11            20.001a      17-04-2013      1
 PR13.001   15            41.022b      19-04-2013      1
 PR13.001   15            41.022b      19-04-2013      1

我想做的事情如下:

SELECT Order_id, Customer_id Article_id, Delivery_date, sum(Quantity)
FROM Orders
GROUP BY Order_id

得到类似的东西:

 Order_id   Customer_id   Article_id   Delivery_date   Quantity
 ---------------------------------------------------------------------------
 PR10.001   11            20.001a      17-04-2013      3
 PR13.001   15            41.022b      19-04-2013      2

但是我知道用一个列分组是不可能的,否则你会收到消息:

[...]在选择列表中无效,因为它不包含在聚合函数或GROUP BY子句中.

是否有另一种可能性或解决方法可以按SQL Server中的一个特定列进行分组？

我有这个SQL查询:

SELECT Start,
    ISNULL((SELECT Orders FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'WP'),0) AS Werkplaats_ord,
    ISNULL((SELECT Tijd FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'WP'),0) AS Werkplaats_tijd, 
    ISNULL((SELECT Orders FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'MAG'),0) AS Magazijn_ord,
    ISNULL((SELECT Tijd FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'MAG'),0) AS Magazijn_tijd, 
    ISNULL((SELECT Orders FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'SERV'),0) AS Service_ord,
    ISNULL((SELECT Tijd FROM [pp].dbo.VW_BEZETTING_RAW b2 WHERE b2.Start=b1.Start AND Afdeling = 'SERV'),0) AS …

我的数据库存储了一些我必须使用AJAX获得的文本.这很顺利,但只有当它不包含特殊字符,如ë或ä时.我找到了一些关于这个主题的文章告诉我要改变AJAX请求的字符集,但这些都不适合我.

当我开始使用firebug时,它说了这个标题:
