Read files in a folder

Gets only files in a folder. Set Filter to @.file to list files only. Supply DriveId and FolderId.

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_folder
WITH (
	  DriveId='me'
	  --OR-- Use Shared Drive Id or other User's Drive Id
	  --DriveId='b!GtLN726LE0eXXXXXXXXXXXX'
	  
	  --Path must end with colon
	  ,FolderId='/root:' 	
      --,FolderId='/root:/my-subfolder:'
	  
	  --OR-- (Folder ID)
	  --,FolderId='atLNaXXXXXXXXXXXXxx'
      
	  ,Filter='$.value[?(@.file)]'
	  )
	  
--You can get DriveId by selecting from 'Drives' table.
--You can get FolderId 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_folder
WITH (
	  DriveId=''me''
	  --OR-- Use Shared Drive Id or other User''s Drive Id
	  --DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
	  
	  --Path must end with colon
	  ,FolderId=''/root:'' 	
      --,FolderId=''/root:/my-subfolder:''
	  
	  --OR-- (Folder ID)
	  --,FolderId=''atLNaXXXXXXXXXXXXxx''
      
	  ,Filter=''$.value[?(@.file)]''
	  )
	  
--You can get DriveId by selecting from ''Drives'' table.
--You can get FolderId 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_folder
WITH (
	  DriveId=''me''
	  --OR-- Use Shared Drive Id or other User''s Drive Id
	  --DriveId=''b!GtLN726LE0eXXXXXXXXXXXX''
	  
	  --Path must end with colon
	  ,FolderId=''/root:'' 	
      --,FolderId=''/root:/my-subfolder:''
	  
	  --OR-- (Folder ID)
	  --,FolderId=''atLNaXXXXXXXXXXXXxx''
      
	  ,Filter=''$.value[?(@.file)]''
	  )
	  
--You can get DriveId by selecting from ''Drives'' table.
--You can get FolderId by selecting from ''list_root'' table OR selection from ''list_folder''.'
