Update and left outer join statements

Question

I have two tabels with a relation and I want to update a field in table A. Is it possible to combine update and join in the same query? I googled it but didnt find any working solution?

UPDATE md SET md.status = '3' 
FROM pd_mounting_details AS md 
LEFT OUTER JOIN pd_order_ecolid AS oe ON md.order_data = oe.id

I'm using MS SQL

In mysql the SET clause needs to come after the JOIN. Example:

UPDATE e
    LEFT JOIN a ON a.id = e.aid
    SET e.id = 2
    WHERE  
        e.type = 'user' AND
        a.country = 'US';
