Question

代码运行正常。今天早上，我看到自动化作业运行后，最终填充了重复作业。经过调查，我发现事实表不包含重复项，但其中一个视图包含重复项。如何删除重复的视图？代码如下：

SELECT DISTINCT

我正在使用以下代码检查重复项：选择count（sys_id），编号为[ALJAZEERA \ Naeemf]。[Requests Hierarchy View]按（sys_id）组，编号为count（sys_id）> 1

样本结果数据集如下：

Thera总共有716个重复行。但是，我只分享了一些示例数据

sys_id是唯一标识符！

感谢您阅读和提供任何帮助！

很可能您没有将维连接到唯一键上，并且维中有多个具有此键值的行。这些尺寸变化缓慢吗（可能是类型2）？检查dim.dimEmployee，是否存在具有相同电子邮件地址的行？

select [Email Address], count(*) from dim.dimEmployee group by [Email Address] having count(*) > 1

在视图中删除重复项
