James Taylor updated PHOENIX-1716:
----------------------------------
Fix Version/s: 4.8.0
> queries with to_char() return incorrect results
> -----------------------------------------------
>
> Key: PHOENIX-1716
> URL: https://issues.apache.org/jira/browse/PHOENIX-1716
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.2.0
> Reporter: Jonathan Leech
> Fix For: 4.8.0
>
>
> Using to_char() in a nested query causes it to get confused and return the
> value of the first column twice.
> Example:
> select
> to_char(case when foo < 0 then 18446744073709551616.0 + foo else foo end,
> '0') foo,
> to_char(case when bar < 0 then 18446744073709551616.0 + bar else bar end,
> '0') bar
> from (
> select cast(12345 as bigint) foo, cast(233456 as bigint) bar from
> system."SEQUENCE" limit 1
> );
> Workarounds: Use different but equivalent format strings in each column, make
> subtle changes to the beginning of the columns; e.g. change to 0 + case
> when..., 0.0 + case when....
