Solution:

We don't provide the customize SQL query support, but you can still get the detail SQL query by these:

1) Create many-to-many relationship between two post types

2) Create a view to retrieve the related posts

OR Use Post relationship API to retrieve the related posts in your website

Run those page/post of step2), then you will be able to get those SQL query in details.

Hello,

I've had no success in getting the view I need to work, so I think I'll need to use wpdata tables with a MySQL query.
Can anyone point me in the direction of how to query many2many relationships that has an intermediary with fields?
I'm in way over my head and will probably have to hire someone, but if you can give me some idea of how the relationships are stored.

Thanks,
Scott.
