Proposed changes

when we use sql

select a.name,
tmp.k,
tmp.v
from (
select 'zhangsan' name,
map(1,20,2,30) score
)a lateral view explode_map(score) tmp as k,v;
errCode = 2, detailMessage = Unknown table 'v'

after this pr:

mysql> select a.name, tmp.k, tmp.v from ( select 'zhangsan' name, map(1,20,2,30) score )a lateral view explode_map(score) tmp as k,v;
+----------+------+------+
| name | k | v |
+----------+------+------+
| zhangsan | 1 | 20 |
| zhangsan | 2 | 30 |
+----------+------+------+
2 rows in set (0.31 sec)
