*= is actually used at my work place.  Thanks for the answer.

That is a left outer join. It's mixing new and old styles of joining tables.
Not sure if there's a benefit to the mix, but I reckon this is clearer:

SELECT a.id, b.name
FROM a
INNER JOIN b ON a.id = b.id
LEFT OUTER JOIN b ON a.id = b.id

Is this code actually used or an example for the question?
