【问题描述】：

我的密码：

String databaseURL  = "jdbc:ucanaccess://Orders.accdb";
        
        try 
            Connection connection = DriverManager.getConnection(databaseURL);
            
            System.out.println("Connected to MS Access database");
            
            String sql = "INSERT INTO Orders (Order Date, Completion Date, Starting Date, Machine, Client, Job Name, Comment) VALUES"
                        + "('9/30/2021', '9/30/2021', '9/30/2021', 'Okay', 'Okay', 'Okay', 'Yes you are Okay')";
            
            Statement statement = connection.createStatement();
            int rows =  statement.executeUpdate(sql);
            
            if (rows > 0 )
                System.out.println("A new thing has been inserted.");
            
            
            connection.close();
         catch (SQLException ex) 
            Logger.getLogger(OrdersTestCode.class.getName()).log(Level.SEVERE, null, ex);
        

我的错误

我设置了一个断点，它在 int Rows 行崩溃。我确信这可能是我的 SQL 语句，但我可能错了。有人可以帮我找出问题所在吗？

【问题讨论】：

表存在吗？

【参考方案1】：

尝试使用正确的 Access SQL 语法：

String sql = "INSERT INTO Orders ([Order Date], [Completion Date], [Starting Date], Machine, Client, [Job Name], Comment) VALUES "
                 + "(#9/30/2021#, #9/30/2021#, #9/30/2021#, 'Okay', 'Okay', 'Okay', 'Yes you are Okay')";
