Subject regexp_replace can not work well with flatten function
Date Mon, 10 Nov 2014 23:03:52 GMT
Hi Team,

DRILL-1679 is opened for this issue:
regexp_replace can not work well with flatten function.
I tested on latest 0.7 build.

with tmp as
> (
> select 1 as fixedcolumn,flatten(columns) as newcol from `b.csv`
> )
> select regexp_replace(cast(tmp.newcol as VARCHAR),'a','b')  from tmp;
> $ cat b.csv
> aaaa,bbbb,cccc


Is it a valid bug?

Thanks,
Hao
