List folders in a parent folder

Gets folders within a specific parent folder in a document library. You can filter by path or ID.

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_folders
WITH (
  -- Drive (SharePoint Document Library)
  DriveId='b!GtLN726LE0eY5F2BBNi14wMKmwdpCDFMn1d71ra11GuQ4DORpHy-XXXXXXXXXXXXX'
, SearchPath='/items/01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R' --enter parent folder id in search path
--OR--
--, SearchPath='/root:/myfolder/subfolder:' --You may also use parent folder path rather than id like this under which you like to search 

--exclude self: enter parent folder id to exclude from the list
, Filter='$.value[?(@.folder.childCount !=null && @id!=''01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R'')]' 

)
--You can get DriveId by selecting from 'Drives' table.

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_SHAREPOINT_ONLINE_IN_GATEWAY], 'SELECT * FROM list_folders
WITH (
  -- Drive (SharePoint Document Library)
  DriveId=''b!GtLN726LE0eY5F2BBNi14wMKmwdpCDFMn1d71ra11GuQ4DORpHy-XXXXXXXXXXXXX''
, SearchPath=''/items/01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R'' --enter parent folder id in search path
--OR--
--, SearchPath=''/root:/myfolder/subfolder:'' --You may also use parent folder path rather than id like this under which you like to search 

--exclude self: enter parent folder id to exclude from the list
, Filter=''$.value[?(@.folder.childCount !=null && @id!=''''01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R'''')]'' 

)
--You can get DriveId by selecting from ''Drives'' table.')

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_SHAREPOINT_ONLINE_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM list_folders
WITH (
  -- Drive (SharePoint Document Library)
  DriveId=''b!GtLN726LE0eY5F2BBNi14wMKmwdpCDFMn1d71ra11GuQ4DORpHy-XXXXXXXXXXXXX''
, SearchPath=''/items/01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R'' --enter parent folder id in search path
--OR--
--, SearchPath=''/root:/myfolder/subfolder:'' --You may also use parent folder path rather than id like this under which you like to search 

--exclude self: enter parent folder id to exclude from the list
, Filter=''$.value[?(@.folder.childCount !=null && @id!=''''01SUOJPKA3E3JKEBRLFRBYGIPBARUP3A2R'''')]'' 

)
--You can get DriveId by selecting from ''Drives'' table.'
