Sql “OLE DB提供程序”；微软.Jet.OLEDB.4.0“；“用于链接服务器”；（无效）“；报告了一个错误

尝试更改：

SET@ExcelString='excel8.0；数据库='+@fn

致：

SET@ExcelString='excel8.0；数据源='+@fn+'；'

在后面的分号上不是100%确定，所以请尝试使用或不使用
有时SQL Server在导入时会遇到麻烦，这可能不是您的错。我的代码前一天运行正常，但第二天没有变化。非常令人沮丧

确保对有问题的DB运行此命令（它不是主DB命令）：

DBCC FREEPROCCACHE

我随机尝试了这个，它似乎重置了一些东西。
问题是什么？你试过什么？
