我最近做了一个SQL PIVOT，并且发现它并不完全正确。下面是我使用的是什么SQL Pivot不会汇总所有结果
SQL Server 2005中 供应商数据库使用供应商的观点 - 我不能创建额外的表或视图或直接查询数据表（长的故事）
我查询一组数据每月有多个条目，并将其与第二组进行联合以使我称之为数据集。我正在使用CASE WHEN来分组对象（即结果与dbid 1,7和10为'a'，2,3和9为'b'等。
我旋转数据集以显示体积总和
我的问题是针对其中一个列，它没有计算数据集中所有结果，看起来是一年中的一个月，在更仔细的调查中，我看到那些缺失的数据似乎是在哪里在下面的查询中，两行数据具有相同的N_Entered值）。
我已经设法重新使用通用查询（下面）的问题。我已经在sql server express 2008 r2和sql server 2005上运行了这个，我得到了相同的结果 - 它们是
Begin_Time总计A苹果B香蕉香蕉C胡萝卜胡萝卜D狗狗 2014-02-01 00:00 ：00.000 174732 44000 4591 581 208
2014年2月B的总和为4594，但是此查询返回4591.您将注意到表1中2月的'B'的两个条目的N_Entered为'3'。
如果我删除，工会与表2的数据集的部分 - 我得到正确的答案 - 4594.
我的$1米问题（S）是
- 我怎样才能得到正确的结果一个枢轴？
- 对于我自己的学习 - 我做错了什么？此代码，我生产的查询之间
差异是
我从意见的生产，而不是使用表变量在生产跨度 结果一年多选择，我刚离开“DATEDIFF子句是尝试并尽可能保持接近。
非常感谢！
