Read files from group or other user's drive

Gets files from a group or another user's drive. Use SearchType='children' (recursive may not work in all cases). Supply GroupOrUserId, DriveId, and SearchPath.

Standard SQL query example

This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.

SELECT * FROM list_files
WITH(
	  GroupOrUserId='/groups/138eb458-84f0-4928-bbe6-df663bd1fcea'
	, DriveId='me'
  --OR-- Use Shared Drive Id or other User's Drive Id
  --,DriveId='b!GtLN726LE0eXXXXXXXXXXXX'
  
	, SearchType='children'
	, SearchPath='/root:/folder/subfolder:'
  --, Filter='$.value[*]' --list both files and folders
  --, Filter='$.value[?(@.folder.childCount != null)]' --list only folders
)

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_ONEDRIVE_IN_GATEWAY], 'SELECT * FROM list_files
WITH(
	  GroupOrUserId=''/groups/138eb458-84f0-4928-bbe6-df663bd1fcea''
	, DriveId=''me''
  --OR-- Use Shared Drive Id or other User''s Drive Id
  --,DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
  
	, SearchType=''children''
	, SearchPath=''/root:/folder/subfolder:''
  --, Filter=''$.value[*]'' --list both files and folders
  --, Filter=''$.value[?(@.folder.childCount != null)]'' --list only folders
)')

Using EXEC in SQL Server (handling larger SQL text)

The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements. This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).

Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_ONEDRIVE_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM list_files
WITH(
	  GroupOrUserId=''/groups/138eb458-84f0-4928-bbe6-df663bd1fcea''
	, DriveId=''me''
  --OR-- Use Shared Drive Id or other User''s Drive Id
  --,DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
  
	, SearchType=''children''
	, SearchPath=''/root:/folder/subfolder:''
  --, Filter=''$.value[*]'' --list both files and folders
  --, Filter=''$.value[?(@.folder.childCount != null)]'' --list only folders
)'
EXEC (@MyQuery) AT [LS_TO_ONEDRIVE_IN_GATEWAY]
