Glad that your queries worked. Please do let us know if any further
problems.
The bug is with EXISTS. Right now Phoenix does not handle aggregate
function calls correctly within an EXISTS subquery or EXISTS nested
subquery. I have opened a JIRA:
https://issues.apache.org/jira/browse/PHOENIX-1923.
I don't think that the bug is with EXISTS. As you can see with the query
from my last email, it contains a nested correlated subquery which contains
an aggregate within *EXISTS* and it worked after replacing the reference to
the outer table (W.rowId) with a reference to the inner subquery table
Thanks for the explanation. I see what you mean. I will also try testing a
query that contains nested correlated subqueries with multiple level outer
reference, and with using IN instead of EXISTS and I will see if it
produces an error.
Best,
Khaleel

Hi Khaleel,
Thanks for looking into the problem! But there IS a bug with EXISTS having
an aggregate function, say max(H.timestamp) as used in your very first
query that did not work. Otherwise, if subquery is SELECT * or SELECT
column1 or SELECT substr(column1), it's fine coz there is no
Thank you in advance! Just let me know.
Thanks,
Maryann
