How to extract data from multiple flat files to load into corresponding tables in SQL Server 2008 R2 ?

Hi,
          I have to implement the following scenario in SSIS but don't know how to do since I never worked with SSIS before. Please help me.
          I have 20 different text files in a single folder and 20 different tables corresponding to each text file in SQL Server 2008 R2 Database. I need to extract the data from each text file and
load the data into corresponding table in Sql Server Database. Please guide me in how many ways I can do this and which is the best way to implement this job. Actually I have to automate this job. Few files are in same format(with same column names
and datatypes) where others are not.
1. Do I need to create 20 different projects ?
               or
    Can I implement this in only one project by having 20 packages?
             or
    Can I do this in one project with only one package?
Thanks in advance.

As I said I don't know how to use object data type, I just given a shot as below. I know the following code has errors can you please correct it for me.

Hi PKJ,
I modified your VI and it seems to do what you asked, that is, display the data from a file as the data is being added.
Hope it helps!

How to extract data from OMElement object file attachment SOAP Service

We are having Axis2 Tomcat6 Webservice on SOAP WSDL
The Webservice method is like this
public String uploadGpxFile(OMElement omEle) throws AxisFault {
    // Extract file attachment from omEle
   // store in database
   return "ok";
So, I just went through the documentation and executed
omEle.getText();
This printed the attached data like this
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <ns:uploadGpxFileResponse xmlns:ns="..........">
         <ns:return><![CDATA[ MY REQUIRED XML DATA IS HERE ]]></ns:return>
      </ns:uploadGpxFileResponse>
   </soapenv:Body>
</soapenv:Envelope>
So, I essentially want to extract this data and store in database. My simple question is how to do it!
It sounds crazy but, I am quite new to Java. I was actually debugging client and found there is a problem in server and started fixing it!! It would be very helpful if someone helps

Hi,
as far as i know you have to use sql to archive your goal, i.e. write your own methods for every complex sql-statement you want to use. thats the sad thing about the whole ORM-concept.

How to extract data from offline PDF files as batch processing

Hello.
I want to use Adobe Interactive forms as batch processing.
For instances,
1. Users download offline PDF files.
2. Users inputs data on their local PCs.
3. Users upload these PDF files in one folder.
4. Program can read data form PDF files on that folder. and put data to ERP at night.
I' d like to know how to implement a program with Java or ABAP.
Regards.
Koji.

Hi,
It's possible to do it but first be sure that the SAP system can read the directory while your program is executed in background .
Then you have to read the content of the directory and process each file you found.
Look at this standard ABAP object cl_gui_frontend_services , you will find method for browsing a directory and retrieve list of file .
Afterwards you have to process each file , for this have a look at this wiki code sample i wrote for processing inbound mail with adobe interactive form, it should help you [Sample Code for processing Inbound Mail with Adobe Interactive Forms|https://www.sdn.sap.com/irj/sdn/wiki?path=/display/snippets/sampleCodeforprocessingInboundMailwithAdobeInteractive+Forms]
Hope this help you .
Best regards.

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?
