I am building a report outside of Drupal that pulls data from a Drupal 8 database. The report shows titles of different nodes and I want to link those titles to the web page for that content. This is working fine if I use the standard /node/X path, but I would like to use the URL alias. I don't want the url alias of the node itself (which I did find thanks to this Which mysql tables contain the URL Alias path data? post). Our content is related to groups, so I want to use the URL alias that is created as part of the group entity relation.

enter image description here

At first I checked the url_alias table, using this query to look for the node id in the source field, but I didn't find the alias set up for that node :

select u.alias 
from url_alias u
where u.source LIKE '%4806%'

Then I tried to check the group tables. I only find 5 tables starting with group in the MySQL schema, and I didn't find the URL alias for the entity reference in any of them:

  • group_content
  • group_content__group_roles
  • group_content_field_data
  • groups
  • groups_field_data

Does anyone know where that URL alias from the group relation is stored in the MySQL schema?

    All URL aliases that use the core system are in the url_alias table. It's not just for nodes. From the screenshot it looks like whatever entity type that is uses the core alias system (the checkbox is a giveaway), so you should find its aliases in the same table

  • Thanks Clive, I've edited my answer above to show that I thought I tried that. But now I realize that the group aliases do not have the node id in the source field, so that's why my query didn't work. Querying url_alias table looking for the known alias in the alias field, I was able to find it now. If you want to write your comment as an answer, then I'll accept it.

As Clive stated in the comment, all aliases are in the url_alias table.

You should join it with the og_membership table, to take the url alias of the node's group.

So, for a node with id 100, the script should look like:

select u.alias 
from og_membership og, url_alias u
where concat('node/', og.gid) = u.source
and og.etid = 100 and og.group_type like 'node'

    This structure is for Drupal 7.

  • Thanks for pointing that out Maria. Sorry that I forgot to mention the version. I am using Drupal 8, and I don't see an og_membership table. I've edited the question to mention the version.

url_alias is path_alias in drupal 8

select n.nid, n.vid, n.type, pa.path, pa.alias, pa.status
from node n 
inner join path_alias pa on pa.path = concat('/node/', n.nid);
