在截断和插入几百万行的几个较大的存储过程中，我们在 DMS 中至少有 30% 或更多的时间出现死锁。但是，只有一个查询正在运行，所以我看不出死锁是我的错：
Msg 110802, Level 16, State 1, Line 1

和：

这点是否明显需要检查或修复？还是 Azure 支持案例是解决问题的最佳途径？
更新：支持案例 115111713384329 已针对此问题开放
更新：我们的 SQL DW 在 2016 年 3 月 4 日获得了一个新的更新，据说它修复了这个问题。（我不能按需复制它，所以我不能肯定地说。）如果你运行“select @@version”，那么 10.0.8224.5 或更高版本应该有修复。如果您还没有修复程序，我想打开一个支持案例并请求它或等待几周会让您得到修复程序。
