视觉FoxPro连接问题 [英] Visual foxpro connection problem

问题描述

海，


在这里，我使用foxpro驱动程序提取提示数据.但是运行该代码后，我得到了错误

错误[42000] [Microsoft] [ODBC Visual FoxPro驱动程序]命令包含无法识别的短语/关键字.在ada.Fill(ds，"emp1")附近；

请给我一个思路以清除此问题，请plz告诉我，这是一种将提示文件直接提取到我们的.net应用程序中而不进入foxpro数据库的好方法.plz请记住，我仅对foxpro使用连接字符串，而不是数据库.查询适用于此.请清除我的疑问.

Hai,


Here I am using foxpro driver for extracting tally datas.But after running that code i am getting error

"ERROR [42000] [Microsoft][ODBC Visual FoxPro Driver]Command contains unrecognized phrase/keyword." near ada.Fill(ds, "emp1");

Please give me idea to clear this and plz tell me Is this a good way to extract tally files directly into our .net application without entering into foxpro database.Plz remember that I am using only connection string for foxpro.Not the database.The sql query is suitable for this.Plz clear my doubt.
