當我嘗試通過單擊SQL按鈕在Spotfire的信息鏈接中編寫查詢時，我甚至能夠執行復雜的查詢。SPOTFIRE - 嘗試在信息鏈接中執行查詢時出錯
但是當我嘗試這個非常簡單的一個，它失敗
Select * from Table_name where Date_Value IS NOT NULL
是否有人可以幫我一個解決方案。我試過Date_Value = ''但這並沒有給出正確的價值。我需要它null。

請更新您的問題，包括錯誤。 – niko
Hi Niko，由於我無法發佈完整的錯誤信息，請找到它說轉換失敗的部分 - Spotfire.Dxp.Data上的InformationModelException： 無法獲取數據：[tibcosoftwareinc] [SQLServer JDBC驅動程序]不支持的數據轉換。 （HRESULT：80131500） –
您應該能夠在問題中包含完整的錯誤。請點擊「spotfire」標籤下的「編輯」鏈接並更新它。我對這個問題可能有所瞭解，但我不想提供不正確的信息。 – niko
