我有大量的 Visual FoxPro db 文件，我试图将它们导入一个空的 SQL 2008 Express 数据库。当我运行 SQL 导入和导出向导时，一切似乎都很好。当我到达映射部分时，我可以单击预览并查看所选 FP 表中的数据。当我单击编辑映射或下一步时，我得到：
===================================
Column information for the source and destination data could not be retrieved.
"eqr_sellers" -> [dbo].[eqr_sellers]:
- Cannot find column -1.
(SQL Server Import and Export Wizard)
===================================
Cannot find column -1. (System.Data)

任何见解将不胜感激。
