在SQL Server 2008中选择查看和联合以及死锁

涉及公共基表的两个SQL语句使用UNION进行组合。在SQL Server 2008中选择查看和联合以及死锁

此查询由业务对象生成和报告工作了一段时间。

最近，我们开始看到以下错误，当运行报告对生产Datamart的

消息1205，级别13，状态2，行1个
事务（进程ID 121）已被死锁的线程|通信缓冲区资源与另一个进程并被选为死锁受害者。重新运行交易。

我复制了查询，并具有行大约相同数量的PROD发展运行它，它是在那里工作，但是当在生产中运行它给了我同样的错误如上。

添加查询提示：与（NOLOCK）你不认为当查询运行将得到更新的数据？ – 2014-01-23 07:10:04

你有索引吗？也许你的查询正在执行锁定整个表的表扫描。 –

@drewlander我已添加NOLOCK的问题仍然存在某种程度dono为什么！ –

这不是典型的僵局，以及典型的僵局调试技术将在这里工作。您在“线程|通信缓冲区资源”上死锁，而不是数据页面。另外，这对于任何其他人在我们的本地计算机上进行复制和调试都是非常困难的情况。

因为它出现在SELECT和FROM子句几乎是一样的，你可以改写这个通过简单地让你的WHERE子句四个手术室。它需要做着离开加入到

其中（A IS NOT NULL和B = 1）或（IS NOT NULL和B = 2）或（IS NULL和B = 0）

正如警告，我的方法与将UNION更改为UNION ALLs的效果相同，这意味着如果满足两个条件集合，则不会获得重复行。这可能是一件好事，这可能是一件坏事，但这绝对是你应该注意的事情。

如果不为你工作，只是不断简化，直到你摆脱僵局。可能开始考虑执行计划以查找可以提高效率的索引更改，从而使使用更少资源的查询处于死锁状态。甚至可以使它成为一个表值函数，您可以单独运行每个函数，并将结果放入临时表中，然后返回生成的临时表。

有了它为奇数的情况下，你不会找到它的多文档，并推测答案像我可能是你将能够在不与微软打开的情况下做的最好。
