Jonathan Leech commented on PHOENIX-1716:
-----------------------------------------

this no longer seems to be an issue in 4.7. Was probably fixed somewhere between 4.3 and 4.7 along with another bug.

> 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....
