將字符串轉換爲唯一標識時轉換失敗

Question

當我運行我的最終查詢時，出現上述錯誤。我已經正確設置了我的表格格式，如果我單獨運行我的@ProdTotal查詢，我會得到正確的數據，如果我運行最後的@Sales_Prod查詢，而不帶入pt.Production_Volume，則會得到相同的數據。

該錯誤特別指向Line 99，這是INSERT INTO @Production開始的位置。 如果我的pt.Production_Volume設置爲DECIMAL(18,6)，爲什麼會出現錯誤？是因爲我使用了CASE聲明嗎？

這裏是我的整個查詢：

TL;博士：我越來越開始在我INSERT INTO @Production線上面的錯誤，我不知道爲什麼。

在此先感謝大家！

根據聲明，Plant_Number是唯一標識符。但是您試圖插入pl.plant_name作爲plant_Number。 SELECT語句中的列有錯誤的順序
