Qserv group by question

Hi

It seems that you can’t have more than one attribute in a group by clause eg

this works

select multiframeID,min(extNum),count(*) from MultiframeDetector where multiframeID < 100000 group by multiframeID

this does not

select multiframeID,extNum,count(*) from MultiframeDetector where multiframeID < 100000 group by multiframeID,extNum

-> ERROR 4120 (Proxy): Unable to return query results:

Is this expected behaviour?

Cheers
Mike

Hi Mike,

No, that should work – we’re looking into it for you now and will update here (we’re also looking at the director match table issue previously reported, now that we’re back from the holiday break.)

cheers,
