Open camelia-c opened 10 years ago

Add support for (left / right/ full) outer join

rmetzger commented 10 years ago

Hi, sorry for being a bit unresponsive these days. I'm at the CeBIT.

Its certainly a very nice topic, but there are some unresolved issues with my inner join implementation. Namely, it is not working since I did not implement everything that is required. More importantly, I have not found out yet how to get the join key indexes from the input relations. Regards, Robert

Hey @camelia-c, have you started to work on this? I know its a difficult task, so its totally okay to share your work in progress.
