I don't see any support for MEDIAN in the Trafodion SQL parser.

There is a getMedian() aggregator function in our endpoint coprocessor 
implementation and also in the TransactionalAggregationClient, so I would think 
we have support for this function.  I haven't tested it personally.

Hi trafodioners,

Can anyone please tell me does Trafodion support median function or similar 
window function as Oracle has? If not, do we have another way to realize this?

Select
median(fee_sum_before),
avg(fee_sum_before),max(...),
min(...)
  from ta_user_property;


Best regards,
Yuan
