Issue Number: close #xxx
## Problem summary
if the order by keys are not simple slot in sort node, the order by exprs
have to been added to sort node's output tuple. In that case, we need add a
project node above sort node to eliminate the unused order by exprs. for
example:
WITH t0 AS
(SELECT DATE_FORMAT(date,
'%Y%m%d') AS date
FROM cir_1756_t1 ), t3 AS
(SELECT date_format(date,
'%Y%m%d') AS `date`
FROM `cir_1756_t2`
GROUP BY date_format(date, '%Y%m%d')
**ORDER BY date_format(date, '%Y%m%d')** )
SELECT t0.date
FROM t0
LEFT JOIN t3
ON t0.date = t3.date;
before:
