Does the "Show value in foreign key columns" preference work with SQL Server

I just noticed this preference, and reading about it, it sounds like a great way to use drop-down lists inside HeidiSQL. I couldn't be more thrilled!

But, I can't get it to work with SQL Server. Is this limited to MySQL only?

This is currently limited to MySQL/MariaDB. Mainly due to the reason that I don't know a way of getting foreign relations between MSSQL columns/tables. If you create a ticket on GitHub with some proper starting documentation on that topic I can probably add it?

Found a good example in the MS docs, and I'd link it here, but I don't have enough posts to include HTTP links in my post.

Basically:

SELECT   
    f.name AS foreign_key_name  
   ,OBJECT_NAME(f.parent_object_id) AS table_name  
   ,COL_NAME(fc.parent_object_id, fc.parent_column_id) AS constraint_column_name  
   ,OBJECT_NAME (f.referenced_object_id) AS referenced_object  
   ,COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS referenced_column_name  
   ,is_disabled  
   ,delete_referential_action_desc  
   ,update_referential_action_desc  
FROM sys.foreign_keys AS f  
INNER JOIN sys.foreign_key_columns AS fc   
   ON f.object_id = fc.constraint_object_id   
WHERE f.parent_object_id = OBJECT_ID('<tablename>');

I've added a GitHub issue too, #150
