[SPARK-18863][SQL] Output non-aggregate expressions without GROUP BY in a
subquery does not yield an error
## What changes were proposed in this pull request?
This PR will report proper error messages when a subquery expression
contain an invalid plan. This problem is fixed by calling CheckAnalysis for the
plan inside a subquery.
## How was this patch tested?
Existing tests and two new test cases on 2 forms of subquery, namely,
scalar subquery and in/exists subquery.
````
-- TC 01.01
-- The column t2b in the SELECT of the subquery is invalid
-- because it is neither an aggregate function nor a GROUP BY column.
select t1a, t2b
from t1, t2
where t1b = t2c
and t2b = (select max(avg)
from (select t2b, avg(t2b) avg
from t2
where t2a = t1.t1b
)
)
;
-- TC 01.02
-- Invalid due to the column t2b not part of the output from table t2.
select *
from t1
where t1a in (select min(t2a)
from t2
group by t2c
having t2c in (select max(t3c)
from t3
group by t3b
having t3b > t2b ))
;
