Question

有人可以告诉我以下代码有什么问题吗？

public static void Insert(String Name) {
    Connection connection = null;
    Statement st = null;
    try {
        Class.forName("org.sqlite.JDBC");
        connection = DriverManager.getConnection("jdbc:sqlite:E:\\test.db");
        connection.setAutoCommit(false);
        st = connection.createStatement();
        String sql = "INSERT INTO Accounts (Name,Password,Level) " +
                   "VALUES (Name, 'passhere', 32 );"; 
        st.executeUpdate(sql);

        st.close();
        connection.commit();
        connection.close();
    } catch (Exception e) {
        System.err.println(e.getClass().getName() + ": " + e.getMessage());
    }
    System.out.println("Records created successfully");
}

另外我得到这个错误java.sql.SQLException：没有这样的列：名称

您没有在您的“值”子句中的“名称”字符串周围添加单引号。

String sql = "INSERT INTO Accounts (Name,Password,Level) " + "VALUES ('Name', 'passhere', 32 );";

通过函数将变量传递到表中
