UserErrorSqlBulkCopyInvalidColumnLength-Azure SQL數據庫

Question

我正在使用Azure Data Factory將Salesforce配置為Azure SQL數據庫數據副本。 列長度​​似乎存在問題，但是我無法確定哪一列實際上是引起問題的原因。

我如何才能更深入地了解導致問題的原因？ 或哪一列真正無效？

Answer 1

我在嘗試將字符串從源復制到目標時看到了該錯誤，但是在目標上接收該字符串的列比源短。

我的建議是確保選擇的數據類型在目標位置足夠大，以便它們可以從源接收數據。 確保接收器也具有預覽中顯示的列。

要確定可能涉及的列，請從源中一一排除大列。
