[jira] [Created] (DRILL-2688) Use of ORDER BY on right side of
Union All results in SqlValidatorException
Khurram Faraaz created DRILL-2688:
-------------------------------------
Summary: Use of ORDER BY on right side of Union All results in SqlValidatorException
Key: DRILL-2688
URL: https://issues.apache.org/jira/browse/DRILL-2688
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.9.0
Environment: 9d92b8e319f2d46e8659d903d355450e15946533 | DRILL-2580: Exit early from HashJoinBatch if build side is empty | 26.03.2015 @ 16:13:53 EDT
Reporter: Khurram Faraaz
Assignee: Jinfeng Ni
Order by in the right leg of Union All results in SqlValidatorException.
Executing the query individually (the query that is on right side of Union All) gives expected results and no Exceptions are seen. However, executing the query as part of the right leg of Union All results in Exception.
Tests were executed on 4 node cluster on CentOS. Both sides of Union All got input from CSV files.
The query below returns correct results when executed individually. (this is the same query used on right side of Union All query)
{code}
0: jdbc:drill:> select columns[0] from `testWindow.csv` t2 where t2.columns[0] is not null group by columns[0] order by columns[0];
+------------+
| EXPR$0 |
+------------+
| 10 |
| 100 |
| 113 |
| 119 |
| 2 |
| 50 |
| 55 |
| 57 |
| 61 |
| 67 |
| 89 |
+------------+
11 rows selected (0.265 seconds)
{code}
Note that the Union All query works when there is no order by in the right leg.
{code}
0: jdbc:drill:> select columns[0] from `employee.csv` t1 where t1.columns[0]=1 union all select columns[0] from `testWindow.csv` t2 where t2.columns[0] is not null group by columns[0];
+------------+
| EXPR$0 |
+------------+
| 1 |
| 100 |
| 10 |
| 2 |
| 50 |
| 55 |
| 67 |
| 113 |
| 119 |
| 89 |
| 57 |
| 61 |
+------------+
12 rows selected (0.175 seconds)
{code}
In this case we do use an order by on the right side of Union All, which results in SqlValidatorException. Same query as above, except that we have an order by clause in the query on the right side of Union All.
{code}
0: jdbc:drill:> select columns[0] from `employee.csv` t1 where t1.columns[0]=1 union all select columns[0] from `testWindow.csv` t2 where t2.columns[0] is not null group by columns[0] order by columns[0];
Query failed: SqlValidatorException: Column 'columns' not found in any table
Error: exception while executing query: Failure while executing query. (state=,code=0)
