Read files in a folder path (recursive)

Gets files in a folder and its subfolders. Use list_files with DriveId, SearchPath (e.g. /root:/myfolder/subfolder:), and optional Filter and OrderBy. New or non-indexed files may not appear immediately.

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(
     Filter='$.value[*]' --list both files and folders
   --Filter='$.value[?(@.file.mimeType != null)]' --list only files
   --Filter='$.value[?(@.folder.childCount != null)]' --list only folders
	,DriveId='me'
  --OR-- Use Shared Drive Id or other User's Drive Id
  --,DriveId='b!GtLN726LE0eXXXXXXXXXXXX'
  --,SearchPath='/root'	--folder path
  --,SearchPath='/root:/myfolder:'	--folder path (make sure to start with slash and end with colon)
	,SearchPath='/root:/myfolder/subfolder:' --folder path nested (make sure to start with slash and end with colon)
    ,OrderBy='lastModifiedDateTime desc'
)		
--You can get DriveId by selecting from 'Drives' table.
--You can get SearchPath by selecting from 'list_root' table OR selection from 'list_folder'.

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_ONEDRIVE_IN_GATEWAY], 'SELECT * FROM list_files
WITH(
     Filter=''$.value[*]'' --list both files and folders
   --Filter=''$.value[?(@.file.mimeType != null)]'' --list only files
   --Filter=''$.value[?(@.folder.childCount != null)]'' --list only folders
	,DriveId=''me''
  --OR-- Use Shared Drive Id or other User''s Drive Id
  --,DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
  --,SearchPath=''/root''	--folder path
  --,SearchPath=''/root:/myfolder:''	--folder path (make sure to start with slash and end with colon)
	,SearchPath=''/root:/myfolder/subfolder:'' --folder path nested (make sure to start with slash and end with colon)
    ,OrderBy=''lastModifiedDateTime desc''
)		
--You can get DriveId by selecting from ''Drives'' table.
--You can get SearchPath by selecting from ''list_root'' table OR selection from ''list_folder''.')

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(
     Filter=''$.value[*]'' --list both files and folders
   --Filter=''$.value[?(@.file.mimeType != null)]'' --list only files
   --Filter=''$.value[?(@.folder.childCount != null)]'' --list only folders
	,DriveId=''me''
  --OR-- Use Shared Drive Id or other User''s Drive Id
  --,DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
  --,SearchPath=''/root''	--folder path
  --,SearchPath=''/root:/myfolder:''	--folder path (make sure to start with slash and end with colon)
	,SearchPath=''/root:/myfolder/subfolder:'' --folder path nested (make sure to start with slash and end with colon)
    ,OrderBy=''lastModifiedDateTime desc''
)		
--You can get DriveId by selecting from ''Drives'' table.
--You can get SearchPath by selecting from ''list_root'' table OR selection from ''list_folder''.'
