You can really approach this type of problem (storing files for later retrieval) one of two ways:
1. store a link in the database (easier up front, but you need a place to store the actual data)
2. store the blob right in the database (more complex up front, easier for migrations)
Since you mention storing a FSO into a BLOB - I assume you've settled on option #2.

Another way is highlighted in my article here:
Uploading and downloading files to/from a SQL Server database[

Hope this helps!
