使用 Astera Centerprise Data Integrator 7 写入表时出错

Question

我正在使用 Astera Centerprise Data Integrator 版本 77 创建一个简单的流程，将我的数据从 excel 文件转储到数据库目标。

但是，在写入数据时，我的流程遇到以下错误：

Error executing bulk insert into table [dbo].[StgSourceCopied_ChildStatistic_CBM]. Insert bulk failed due to a schema change of the target table.

下面是我的流程的堆栈跟踪：

Go 到数据库目标属性中的布局构建器并单击刷新按钮，这将带来表的更新模式。 之后您可能需要重新映射您的字段。
