Why so many downvotes and no comments?

Try with:

SELECT 
    oh.ser_id,
    oh.sales_vertical,
    oh.partner_id,
    oh.category,
    oh.sub_category,
    oh.stage_id,
    oh.exp_revenue,
    oh.action,
    oh.action_date,
    oh.title_action,
    oh.date_action,
    oh.details,

    rp.tri_title,
    rp.tri_subtitle

FROM opportunity_history AS oh
  INNER JOIN res_partner AS rp
    ON rp.partner_id = oh.partner_id
