Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.21.0
Reporter: James Turton

apache drill> SELECT
2..semicolon> *
3..semicolon> FROM
4..semicolon> (SELECT
5..........)> education_level,
6..........)> salary,
7..........)> marital_status,
8..........)> extract(year from age(birth_date)) age
9..........)> FROM
10.........)> cp.`employee.json`)
11.semicolon> PIVOT (
12.........)> avg(salary) avg_salary, avg(age) avg_age FOR marital_status IN ('M' married, 'S' single)
13.........)> );
