SQL 查询行为不当。

Question

我是一名新手开发人员，但我当然知道一旦编写的脚本应该以某种方式运行，但在以下用例中，这显然不会发生。

我创建了一个包含 INSERT INTO SELECT 语句的脚本，该语句应该过滤掉重复项并将差异放入 STAGING 表中，并将过去 7 天的记录保存在 STAGING2 表中。我在后端运行 SQL 作业，以确保我的脚本每隔几分钟运行一次。现在，以前和现在发生过的奇怪的事情是作业继续正常工作，我的 FACT 表被正确填充，没有重复，但突然 JOBS 开始失败，因为不知何故重复进入系统。如果有人可以提供帮助，我将分享下面的代码。 （这是几个月来一直正常工作的相同代码）。

感谢我能得到的所有帮助。

谢谢。

您的查询是否在没有过程本身的情况下运行？

查看各种联合选择，您似乎有一个交叉列，其中覆盖了不同的数据类型/空值。如果表结构发生了变化，导致其中一列无法输入空值，这也可能导致您遇到的问题。

尝试从程序中删除查询，看看是否得到任何结果/得到什么结果。
