UserErrorSqlBulkCopyInvalidColumnLength-Azure SQL数据库

Question

我正在使用Azure Data Factory将Salesforce配置为Azure SQL数据库数据副本。 列长度​​似乎存在问题，但是我无法确定哪一列实际上是引起问题的原因。

我如何才能更深入地了解导致问题的原因？ 或哪一列真正无效？

Answer 1

我在尝试将字符串从源复制到目标时看到了该错误，但是在目标上接收该字符串的列比源短。

我的建议是确保选择的数据类型在目标位置足够大，以便它们可以从源接收数据。 确保接收器也具有预览中显示的列。

要确定可能涉及的列，请从源中一一排除大列。
