问题描述

你好b $ b这个看起来很小 - 但它对我不起作用,我在最后几个小时都拉着头发 -  



有一个包含csv文件的文件夹。 2个文件名以INDIA开头,ne文件以MEXICO开头。

我需要将INDIA文件加载到dbo.Indian表和MEXICO文件到dbo.MEXICO表中。



1.我拉了一个ForEach循环文件Enumarator-给出了文件夹路径和文件类型,提到*。*。文件名在变量"User :: FileName"中捕获。

2.然后,在此内部,拉出一个空的序列容器

3.Inside,我拉了一个表达式任务并按照子串(用户:文件名,1,2)=="IN"写入xpression。 &安培;子串(用户:文件名,1,2)==" ME"

4.然后对于第一个先例constaint,我创建了一个DFT来加载dbo.Indian表和第二个Precedent约束,我创建另一个DFT加载到dbo.Mexico表。

5.Flat file conn mgr - >将表达式设置为User:FileName



现在,当我运行包时,它会在上面的步骤3停止-ie)表达式任务 - 不会进行步骤4 - 请参阅随附的截图-pls help!

Hi,
This one looked like a small one - but its not working for me and I am pulling my hair for the last couple of hours - 

There is a folder with csv files. 2 filenames start with INDIA and ne file start with MEXICO.
I need to load INDIA files into dbo.Indian table and MEXICO files into dbo.MEXICO table.

1.I pulled a ForEach Loop File Enumarator- gave the folder path and file type mentioned as *.*. The filename is captured in the variable "User::FileName"
2.Then, inside this, pulled a empty sequence container
3.Inside that, i pulled one Expression task and wrote the xpression as is Substring(user:Filename,1,2)=="IN" & Substring(user:Filename,1,2)=="ME"
4. Then for first precedent constaint, i created a DFT to load dbo.Indian table and for the second Precedent constraint, i created another DFT to load into dbo.Mexico table.
5.Flat file conn mgr -> Set the expression to User:FileName

Now, when I run the package, it stops at the step 3 above -ie) Expression task --its not going to step 4 - pls see the attached screenshot -pls help!
