I might overlook something, but aren't option 2 and 3 the same?


Nope, they are the same. The idea was probably that one of the two didn't have the DISTINCT clause.

Appreciate the question. Had to think for a minute, as I almost never use OUTER joins.

A totally unrelated aside: Back from vacation. Missed the QotD. Didn't miss work.

Spent 17 days in Greece. PLEASE consider a vacation there this year. The place is almost devoid of tourists, and for no good reason. In spite of their troubles, the Greeks were as gracious, warm, and hospitable as ever.

End of totally unrelated comment.

Please don't go. The drones need you. They look up to you.

The five days we were in Athens, right up to the 15th, there was nada. We did see a gathering of about 500 people for a speech. The media has sensationalized the situation and given an overdramatic picture of what is going on.

The result: we went to a beach, about 10 km long, on the western coast of the Peloponnese, and there were 6 people on the beach at noon!

I suspect you actually use outer joins far more frequently than you think.

A left join is the same thing as a left outer join. The outer keyword is optional. :-P

Of course you are correct. My mind must still be on that beach. Thanks for correcting me.

I wish my mind was still on the beach...so jealous. Sounds you had a great time.
