Current capabilities include the extraction of files and metadata about those files from SharePoint document libraries using direct database access. Bypassing application layer security has the benefit of fast and unrestricted access to all of SharePoint. The downside is that the database schema is mostly undocumented.

Extract checked out files not previously checked in

Checked out files which haven't previously been checked in exist because a user added files to a document library but forgot the step of checking the files in -- perhaps after working on draft versions for some time. Now only the user can see the files in the document library. Other users with proper access can navigate to Document Library Settings and Manage checked out files to browse checked out files and take ownership.

Using the Manage checked out files function works well through the browser, but no web service or server-side API exist for retrieving actual file content. During migration of SharePoint 2007, using Sharegate or a custom solution, these files will not be migrated. It makes sense as SharePoint considers those files drafts. But even drafts may hold valuable information and requires proper handling during migration.

To invoke extraction from the command-line:

USAGE: SPDatabaseInspector.exe [--help] --connection-string <connection> --storage-base-path <path> [--with-table-of-content]


    --connection-string <connection>
                          connection string to the SharePoint content database.
    --storage-base-path <path>
                          directory under which extracted files and are stored.
                          adds metadata file at the root of --storage-base-path containing SharePoint 
						  extracted metadata for each file.
    --help                display this list of options.


.\SPDatabaseInspector.exe --connection-string "Server=tcp:<sql-server-host>,1433;Database=<database-name>;Integrated Security=SSPI;Encrypt=True;TrustServerCertificate=True;Connection Timeout=30;" --storage-base-path "c:\temp\output" --with-table-of-content

In case the web application is backed by more than one content database, the command must be run against each content database. Passing arguments as above, a directory structure resembling that of SharePoint is created below c:\temp\output. A server-relative URL to a document library, such as sites/hr/contracts, and a file inside the contracts document library under 2016/finance/johndoe.docx" gets created under c:\temp\output\sites\hr\contracts\2016\finance\johndoe.docx".

Passing the --with-table-of-content option, a CSV file is created under c:\temp\output holding metadata of the documents extracted. The name of the file becomes .csv:

  • DirName -- sites/hr/contracts/2016/finance
  • LeafName -- johndoe.docx
  • Size -- 12345
  • CheckoutUser -- <username>
  • CheckoutDate -- 2011-05-10 10:10:51.000
  • Extension -- docx
  • TimeCreated -- 2011-05-10 10:10:51.000
  • TimeLastModified -- 2011-05-10 10:10:51.000
  • SHA1 -- hash

Make sure --storage-base-path is close to the root of the drive. By limitation of Windows, the path cannot exceed 260 characters or an exception is thrown.

Technical details

In any event, basic knowledge about how the SharePoint content database is organized comes in handy. Across versions, the database schema has changed, so for different versions of SharePoint queries may need to be adjusted. In general, SharePoint in build around the notion that no new tables are created after the product is installed. The creation of site collections, webs, lists, document libraries results only in rows added to existing tables. Actually, the content database contains a surprisingly small number of tables given how complex SharePoint appears through the user interface or API.

A quick warning before running any queries against a live content database. Always run queries with the ´´´with (nolock)´´´ clause added to prevent the query from blocking regular SharePoint operations. SharePoint's application logic may not re-run failed queries because either the query times exceeded a maximum or because out query caused a deadlock.

In addition, SharePoint makes use of triggers, which we don't want to interfere with as that could result in our queries introducing a content database inconsistency.

Lastly, running our custom queries will interfere with cached query execution plans and statistics within the database which (for a short while) can make regular operations slightly slower. The latter is a minor concern that self-corrects while the first two doesn't.

The query to identify draft documents is inspired by the stored procedure called by SharePoint when navigating to Document Library Settings and Manage checked out files. The procedure is named [proc_GetListCheckedOutFiles](https://msdn.microsoft.com/en-us/library/hh632446.aspx] and is called by Microsoft through the CheckedOutFiles property of SPDocumentLibrary (inside Microsoft.SharePoint.dll).
