Extract all attachments from ServiceDesk 7.0 SQL Database

Hi,

I have to extract all attachments from ServiceDesk 7.0 SQL Database from our client's production environment.

I'm looking for a solution or best pratices in doing such operation. I've noticed columns named size before compression and size after compression in DocumentVersion table.

Can I simply use OLE Automation to pull files from Data column (joining DocumentVersionType and one another table to get information about file extension and name) or do I have to use some predefined procedure?

Thanks in advance.
