mssql導出停止在驗證步驟

Question

我正在使用微軟sql服務器，我想導出我的數據庫，但我在最後一步得到一個錯誤。以下是完整報告：

Operation stopped...

- Initializing Connections (Success) 

- Setting SQL Command (Success) 

- Setting Source Connection (Success) 

- Setting Destination Connection (Success)

看起來好像在驗證步驟中有錯誤。

我假設您的Bookid是AutoIncrement字段，並且您正嘗試從其他來源向該表中填充數據。您必須在映射中使用Enable Identity Insert以允許更新Bookid。

此外，請確保您的種子高於您在數據交換中插入的最後一個值，否則當您覆蓋Identity Insert行爲時，您會關閉安全檢查，從而可能會遇到錯誤。
