Excel DB:操作必须使用可更新的查询

Question

对于jdbc程序,我需要连接一个excel数据库.连接成功,但是输入值,它给出"操作必须使用可更新的查询"异常.

这是代码:

        String url="jdbc:odbc:Sample";   //CHANGE THE DATABASE NAME
        Connection conn= DriverManager.getConnection(url,"","");
        PreparedStatement prepstat = null;
        String insert="INSERT INTO [Sheet1$] ([AccountID], [ProjectID], [PositionID]) VALUES (?,?,?)";
        prepstat= conn.prepareStatement(insert);
        prepstat.setString(1, accountID);  
        prepstat.setString(2, projectID);
        prepstat.setString(3, positionID);
        prepstat.executeUpdate();   // this is where the exception occurs

Answer 1

您是否明确声明连接是否在连接字符串中是可读的？

我不熟悉JDBC,但ODBC将是:

"Driver={Microsoft Excel Driver (*.xls)};" & _
"DBQ=C:\MyFolder\MyWorkbook.xls; ReadOnly=False;"

默认情况下,Excel是只读的:http://support.microsoft.com/kb/257819
