这是一个非常古老的线程;然而,我只是偶然发现了一个类似的问题。里面有许多不同记录“格式”的平面文件。许多不同的格式,没有任何特定的顺序,这意味着你可能在一行中有57个字段,然后是下一个1000中的59个,然后是下一个10000中的56个,回到57 ......好吧,认为你有这个想法。
由于缺乏更好的想法,我决定根据每行中的逗号数来打破该文件,然后使用每种类型的SSIS包导入不同的记录类型(现在聚在一起)。
所以这个问题的答案就在那里,用更多的代码来生成文件。
希望这可以帮助有同样问题的人。

好的非常感谢你的回答,但什么我目前正试图做的是算我的头被用分隔符 – largo68 2011-06-13 12:18:38
我知道我的解释是,也许不是完美的分开了,但我怎么可以把屏幕在这里拍摄?,这将有助于definetely更好地理解我的问题 – largo68 2011-06-13 12:53:50
