In a multi-site environment, I have a special need to get post terms (on a custom taxonomy) without the expensive operation of "switching blogs".
I thought I might write my own query to get terms for a given post on a given blog.
I'm looking through the three tables:
wp_3_terms
wp_3_term_relationships
wp_3_term_taxonomy
Yet I cannot see where there is a connection to post_id in any of these.
So the question:
How do terms link with a given post in the database? If I can know that, I can do the rest.

Reset to default 4The posts are related to taxonomies (taxonomy/tag) in the wp_3_term_relationships table, where the object_id column is the post's id, and the term_taxonomy_id is the taxonomy/tag id.
Depending on what you want to accomplish, the solution might be to create the same taxonomies at each blog. This way the tax_query should work as normal.
