Sql CTE+插入错误：字符串或二进制数据将被截断

没有什么背景。我们从报告部门得到一份文件。这是它的工作做了一堆聚合，并推到另一个文件，一个合格的文件

错误显示：

Msg 8152，第16级，第13状态，第2行 字符串或二进制数据将被截断。 声明已终止

---

有人能帮忙吗？有人知道发生了什么吗？

从错误中可以明显看出，对于一个或多个列，您试图设置的数据大于列大小。。我将查看名称列和地址列。一种简单的调试方法是在select子句中的列周围放置一个MAXLEN，并将其与表定义进行比较。

看起来您正试图将10磅的shinola装进一个5磅的袋子中。观察效果非常好。听起来很技术……没错，我注释掉了部分代码，直到我看到它失败的地方。这个错误使我认为内存中的数据将被截断，因此不允许我插入..但我想这是有意义的，因为直到我尝试插入并匹配字段的长度，我才有问题。谢谢你，伙计。
