Subject [jira] [Created] (DRILL-2155) Subquery in projection list that returns scalar result throws an exception
Date Tue, 03 Feb 2015 22:39:34 GMT
Victoria Markman created DRILL-2155:
---------------------------------------

             Summary: Subquery in projection list that returns scalar result throws an exception
                 Key: DRILL-2155
                 URL: https://issues.apache.org/jira/browse/DRILL-2155
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 0.8.0
            Reporter: Victoria Markman
            Assignee: Jinfeng Ni


Since there is no correlation, it shouldn't even plan ...
I think we should throw the same error as in DRILL-1921 (cross join)

{code}
0: jdbc:drill:schema=dfs> select c_integer, (select current_timestamp from t1 limit 1)
from t1;
Query failed: AssertionError: must call validate first
Error: exception while executing query: Failure while executing query. (state=,code=0)

0: jdbc:drill:schema=dfs> select c_integer, (select current_timestamp from t1 limit 1)
b from t1;
Query failed: AssertionError: must call validate first
Error: exception while executing query: Failure while executing query. (state=,code=0)
