透视查询 - 缺少记录

Question

我有一个直到现在才运行的数据透视查询，但是我需要在unpivot查询中指定一个条件，该条件会省略与条件不匹配的行和列值并显示null 。但是，我需要将这些值显示为最终结果的一部分。

我曾尝试使用union来包含缺失值，但无法获得所需的输出。我正在粘贴下面的数据透视查询以及显示的结果以及需要显示的结果。请帮忙。

当前结果 - 在最后两列中看到空值

现在，如果我运行如下的内部unpivot查询，我会得到以下记录/行

            INNER JOIN NEPCCO.OrderStatus os ON o.OrderStatusID = os.OrderStatusID
            INNER JOIN NEPCCO.JobStatus js ON oj.JobStatusID = js.JobStatusID
        WHERE
            o.OrderID IN (6981,6860,6982,6983) AND
            (p.ProductID IN (35,36,37,38,38,40,41,42,43) OR  p.ProductID IN (33,34))

产生以下结果

问题

现在，如果您仔细查看上面的结果集，其订单ID为6860, 6982，但未包含在上述结果中，因为它没有将供应商名称设为Northern Gas Heating Ltd此外，第一个查询显示的结果省略了订单ID 6981, 6983的值，因为它们有不同的供应商。

另外，如果您注意到，在第一次查询中显示记录时，不包括行号为2的值。

我尽我所能但失败了。 @bluefeet，您的专业知识在这里非常需要。任何澄清请问。
