How to connect LOB text file data sources to native SharePoint lists via ODBC and BDLC

Sometimes a direct connection to any system is not available. In this case you can export text files and pull this data into a SharePoint list on a regular base, e.g. once a day. If a primary key is available in your text file, then changed data is updated only.

Here is our sample data source:

Sample Text File to integrate into SharePoint List

Fig.: Sample text file with a text column and some quantity at fixed positions.

First you have to configure your ODBC data source:
  1. Run ODBC Manager 64-Bit (or 32-Bit on a 32-Bit SharePoint)
  2. Run it as Administrator (otherwise no access to System DSN)
  3. Create new System DSN
  4. Add a new Data Source based on Microsoft Access Text Driver named “Textsample”
  5. Select Options, specify *.txt
  6. Disable “Use Current Directory”
  7. Select your Directory
  8. Define Format
  9. Select your Text File, e.g. myfile.txt
  10. Select Format Fixed Length
  11. Define your Columns by Name (min 4 letters), Data Type and Width
  12. Name one column Title to be the primary key later on (or use any other column for that)
  13. Close all Dialogs

Then you can access this data source in the BDLC Settings Dialog:

  1. Create a custom list and go to list settings
  2. Select “Connect to External Data Source”
  3. Select ODBC as Connection Provider
  4. Enter “DSN=Textsample” without “  as Connection String and validate
  5. Enter “select * from myfile.txt” without “ as select statement and validate
  6. Show preview of your first lines and check
  7. Correct ODBC configuration if required
  8. Enter primary key Title and Validate
  9. Add Columns
  10. Check Mapping – All fields should be mapped to columns
  11. Update – All items should be created
  12. Update again – There should be no changes if primary key works
  13. Enable Background updates if required (by default every hour)
  14. Close with OK

And thats the result list:

  1. Display the result list
  2. Update list manually or in background
  3. write-back changes to data source (if supported by driver) 
  4. Create views
  5. Add additional columns and attachements if required
  6. Rename column titles if required
  7. Modify column types, e.g. text to numbers, long text etc. if required
  8. Create subscriptions per RSS or E-Mail if required
  9. Add business workflows on data change, if required
  10. Use search feature as usual
  11. Tag or auto-tag the content for use with Knowledge Management and  Social Networking
  12. ... Just do ALL what you can do with native SharePoint lists ;-) ...

 Text file as native SharePoint List

This sample is with SharePoint 2010. You can do the same with WSS 3.0 / 4.0 or MOSS 2007. The Business Data List Connector for SharePoint 2007 und 2010 shareware you find here.
