Documentum DQL Getting list subfolders from a few folders

Question

everyone! I am starting with Documentum this month and here is my problem. There is multi-select drop-down list with cabinets. I have to choose some of them to get list of inner folders in my result list below. This query:

select * from dm_folder where folder(id($param$))

or

select * from dm_folder where folder($param$)

where param is object_name

works with single drop-down select. I've tried to insert "in"

select * from dm_folder where folder in($param$)

results with

[DM_QUERY_E_SYNTAX]error:  "A Parser Error (syntax error) has occurred in the vicinity of:  select * from dm_folder where folder in" 

or

select * from dm_folder where folder(id in($param$))

results with

select * from dm_folder where folder(id in ('0c0511d48000105',' 0c0511d48000106'))

[DM_QUERY_E_SYNTAX]error:  "A Parser Error (syntax error) has occurred in the vicinity of:  select * from dm_folder where folder(id in"

and return multivalue flag in queries above but it doesn't work. Can someone help, please? Thank you!

Try with this one:

SELECT * FROM dm_folder WHERE r_object_id IN ('0c0511d48000105',' 0c0511d48000106')

I think it's clear where you made an error. Keyword FOLDER you used is function that accepts single value as parameter.

From DQL guide:

The FOLDER predicate
The FOLDER predicate identifies what folders to search. The syntax is:
[NOT] FOLDER(folder_expression {,folder_expression} [,DESCEND])
The folder_expression argument identifies a folder in the current repository. You cannot search a
remote folder (a folder that does not reside in the current repository). Valid values are:
• An ID function
• The ID function (described in The ID function, page 29) identifies a particular folder.
• A folder path
A folder path has the format:
/cabinet_name{/folder_name}
Enclose the path in single quotes. Because cabinets are a subtype of folder, you can specify a
cabinet as the folder.
• The keyword DEFAULT
The keyword DEFAULT directs the server to search the user’s default folder. Note that a user’s
default folder is the same as the user’s default cabinet (because cabinets are a subtype of folders).

Edit 1:

SELECT * FROM dm_folder WHERE ANY i_folder_id IN ('0c0511d48000105',' 0c0511d48000106')

With this query you are looking for folder type objects whose parent is any of the folders specified as the parameter.

Edit 1:

SELECT * FROM dm_folder WHERE i_cabinet_id IN (<list of ids>) 

This will return you all folder objects under cabinet
