Victoria Markman updated DRILL-3326:
------------------------------------
Labels: window_function (was: )
> 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
> Labels: window_function
>
> 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
> See Apache Drill JIRA: DRILL-3195
