請編輯您的[原來的問題（HTTP：/ /stackoverflow.com/questions/3499381/please-correct-me-with-the-sql-query）而不是創建一個新的。 – BoltClock 2010-08-17 05:39:15

@BoltClock：原始問題（3499381）似乎是由於在查詢字符串開始之前省略了@符號而導致的錯誤 - 請參閱Helgi Hrafn Gunnarsson的回答，該回答被接受爲正確。這個問題涉及SQL本身的錯誤;因此，我認爲把它作爲原始問題的重複來解決是錯誤的。我不知道該怎麼做，但我建議重新打開這個問題。 – 2010-08-19 13:13:45

請你回答一些已經留給這個問題的答案。 – 2010-08-19 13:14:53

這只是意味着你忘了你的命令創建@courseId的SqlParameter值。
