Krystal created DRILL-3326:
------------------------------
Summary: Query with unsupported windows function containing "AS"
blocks correct error message
Key: DRILL-3326
URL: https://issues.apache.org/jira/browse/DRILL-3326
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 1.1.0
Reporter: Krystal
Assignee: Sean Hsuan-Yi Chu
The following query contains "AS" using un-supported function first_value
gives incorrect error:
select FIRST_VALUE(voter_id) OVER (PARTITION BY age ORDER BY contributions ROWS
BETWEEN CURRENT ROW AND 1 FOLLOWING) as t from voter_hive;
Error: SYSTEM ERROR: org.apache.drill.exec.exception.SchemaChangeException:
Failure while materializing expression.
Error in expression at index -1. Error: Missing function implementation:
[first_value(INT-OPTIONAL)]. Full expression: --UNKNOWN EXPRESSION--.
After I remove the "AS" keyword, the correct error message is displayed:
select FIRST_VALUE(voter_id) OVER (PARTITION BY age ORDER BY contributions ROWS
BETWEEN CURRENT ROW AND 1 FOLLOWING) from voter_hive;
Error: UNSUPPORTED_OPERATION ERROR: The window function FIRST_VALUE is not
supported
