哪一列式進行經常性' smallint'？ –

M.S - 只是檢查它，沒有一個是smallint，都是varchar –

可能錯誤是在視圖IM_EN_Main_Qualifcation_with_title_vw。你能分享它的內容和數據類型嗎？ – Ako

你應該看看dbo.IM_EN_Main_Qualifcation_with_title_vw。你的問題是，你正在做的事情一樣

c1 + c2

其中C1和C2列，C1是smallint型，C2是文本，並在創建視圖時，C2僅包含數值，但最近的文本數據被添加，其中包含'20PA'。您需要更改視圖以將c1轉換爲文本數據，使用CAST or CONVERT。

EDIT

作爲阿魯娜Raghuna指出的那樣，它被證明是在College_Year柱的一個問題，其中在至少一個情況下，而不是預期的數值包含的文本的爲好。雖然我已經展示了找到答案的方法，但坦率地說，是Aruna，他正在尋找這個問題。思想過程中被用作如下：

檢查列類型，並找出哪些是SMALLINT類型的，這樣我們就知道到哪裏尋找問題
檢查文本列，找出那些包含錯誤消息
可能最後一步是修復任何查詢或與數據一起功能找到文本，所以這種問題不會在未來

剛剛檢查過的意見，數據類型是主要資格：Varchar（20）和Qualification_Title：Varchar（100） –

@ArunaRaghunam，你可以測試你的意見嗎？哪一個包含錯誤？你能描述每一列的數據類型嗎？哪一列包含「20PA」的任何值？ –

我跑了查詢，並沒有列'20PA':( –
