sqlselectgroup-byimpalahaving-clause
cannot use having in impala
where I use "having" in impala sql,I got an error "Could not resolve column/field reference"
select count(dst_ip) as times, dst_ip
from test_mode
group by dst_ip
having times > 1
I don't konw why, impala document is support having https://impala.apache.org/docs/build/html/topics/impala_group_by.html#group_by
Solution
Few databases support reusing aliases defined in the select in the having clause (MySQL comes to mind). I don't think that this belongs to standard ANSI SQL .
In most other databses, such as Impala, you need to repeat the expression:
select count(dst_ip) as times, dst_ip
from test_mode
group by dst_ip
having count(dst_ip) > 1
