Carter Shanklin created PHOENIX-1290:
----------------------------------------
Summary: Cannot alias a FIRST_VALUE column
Key: PHOENIX-1290
URL: https://issues.apache.org/jira/browse/PHOENIX-1290
Project: Phoenix
Issue Type: Bug
Affects Versions: 5.0.0
Reporter: Carter Shanklin
So this works:
{code}
select
ss_customer_sk,
first_value(ss_sold_date_sk)
within group
(order by ss_sold_date_sk asc)
from
store_sales
group by
ss_customer_sk;
{code}
And this doesn't:
{code}
select
ss_customer_sk,
first_value(ss_sold_date_sk) as f
within group
(order by ss_sold_date_sk asc)
from
store_sales
group by
ss_customer_sk;
{code}
You get:
{code}
Error: ERROR 605 (42P00): Syntax error. Unknown function: "FIRST_VALUE".
(state=42P00,code=605)
{code}
Same result if I drop the "as".
This makes it difficult to use first_value in connection with the new subjoin
feature. FIRST_VALUE spits out a very strange column name (in this case it's
null(SS_SOLD_DATE_SK, true, SS_SOLD_DATE_SK)).
Probably affects NTH_VALUE and LAST_VALUE as well.
