在Eclipse中使用SQLite

我在使用MySql數據庫的Eclipse上運行Java實現。現在我想使用SQLite數據庫而不是MySql來實現可移植性。在Eclipse中使用SQLite

我已經定義了以下參數：

System.out.println("Connecting to database..."); 
    Class.forName("org.sqlite.JDBC"); 
    conn1 = DriverManager.getConnection("jdbc:sqlite:media.db"); 
    conn1.setAutoCommit(false);

media.db是我使用SQLite數據庫瀏覽器創建的數據庫的名稱，它包括一個名爲影片表。

該實現在視頻表上運行一些查詢。

我還添加了源碼-JDBC-3.7.2司機從here到LIB夾在WEB-INF和相應地配置構建路徑。

但在運行implemenatation我得到的控制檯以下錯誤：

Connecting to database...

任何幫助，請以什麼錯？

在我看來，當你的應用服務器下運行的代碼不打開正確的數據庫文件，而是一個在你的服務器的工作目錄。 文件根本不包含任何表，因爲它剛剛由SQLite創建。

你可以嘗試使用數據庫文件的絕對路徑，看看問題是否仍然存在？

它現在工作..謝謝！ – Abhishek

確定還有一個問題 - 更新查詢不起作用，即表沒有得到更新。爲什麼會這樣？我檢查了文件屬性及其可寫的權限。 – Abhishek

@ user2464622：你使用'Statement.executeUpdate（）'而不是'Statement.executeQuery（）'作爲你的更新語句嗎？ – thkala

該錯誤顯示沒有視頻表。檢查您的movies.db中的表格視頻。

SqLite Java

給出的完整路徑。

是的，我檢查過它。該表位於media.db中，但它爲什麼沒有檢測到它？ – Abhishek

給出你的數據庫的完整路徑。連接連接= DriverManager.getConnection（「jdbc：sqlite：C：/work/mydatabase.db」） – Shriram
