我有一個桌面應用程序生成在Visual Fox Pro和另一個Web應用程序生成與HTML，CSS，JavaScript和PHP。桌面應用程序與WebDatabase同步數據庫
這些應用程序有不同的數據庫，桌面（interbase）和網絡（MySQL）。我需要在Web應用程序中顯示桌面數據庫中的數據，並使用程序將桌面數據庫轉換爲Web數據庫的格式，然後手動上傳數據。
有什麼辦法可以自動完成這個過程嗎？
我是說，每次在桌面應用程序中輸入新數據時，這些數據都會自動轉換並上傳到Web數據庫中？
感謝您的幫助。
（The Easy Method） 我使用csv格式將數據從vfp數據庫遷移到mysql。首先，我在vfp中創建了一個使用表格並轉換爲csv文件的簡單應用程序。然後我通過PHP將這個文件上傳到服務器上，並使用它的功能從csv中提取數據並插入到mysql數據庫中。
（更多的代碼需要） 正如你們已經討論我直接與MySQL從VFP通過MySQL的ODBC連接溝通也不是那麼困難，如果你有VFP使用SQL Server只是一些日期格式必須改變。
我的代碼如下所示（創建數據庫）
LPARAMETERS par_table, par_extra_field, par_after
IF VARTYPE(par_table) <> "C" OR LEN(ALLTRIM(par_table)) = 0
MESSAGEBOX("Table Not Found to Export", 16, "Table")

ENDIF
IF VARTYPE(par_extra_field) <> "C"
par_extra_field = ""

par_after = ""

你可以簡單地在本地，然後更新數據使用mysql odbc連接器https://dev.mysql.com/downloads/connector/odbc/，更新mysql中的數據。只有當你的mysql可以監聽127.0.0.1（本地主機）以外的其他端口時，此方法纔有效。
有兩個應用程序不能簡單地談談同一個數據庫的原因嗎？ –
是的，桌面應用程序是一個傳統應用程序，我現在無法更改數據庫。在桌面版本中輸入或更新某些內容時，我需要更新桌面和Web數據庫。有沒有辦法？ – Lioo
如果你有狐狸（也許c＃，我不用那種語言編程），你可以編寫一個訪問狐狸表的例程，使用mysql odbc驅動並把數據存入mysql數據庫。我有生產軟件可以做到這一點，所以如果你想要更多的想法，你可以下午我。 – Hank
