顯示我嘗試添加一個保存按鈕，這讓我在Eclipse控制檯此錯誤保存記錄，並在表

，如果有任何人誰能夠在這個問題上共享光明，我會很感激，我自己在這個java中是相當新的。

那個帖子是我這是後我發現我在這裏發佈有關錯誤「java.sql.SQLException：列數不匹配在第1行的值計數」錯誤的問題，其中我修復了SQL後，我發現重繪方法不工作預計，現在所有的工作正常，但是，謝謝 – Levian

您需要在關係語句中轉義文字引號"，如The Java Tutorials: Characters所示。您可以使用連接運算符+來組成您的語句，如The Java Tutorials: Strings中所示。

謝謝，是的問題是在報價中...有時它是在該部分混淆，並使其更難以追蹤...是搞清楚這個錯誤信息是什麼意思 – Levian

編譯器看到兩個屬性，但超過兩個值。對不起，我無法完全從上下文中解析它。 – trashgod

沒關係......它已經解決了，實際上是在這裏發帖，因爲我不知道那個錯誤信息是什麼意思，但進一步的嘗試給了我一個關於這個問題的線索......至少我知道下次如果我得到同樣的錯誤，這意味着我必須更仔細地檢查我的SQL語句與所有報價。 – Levian
