Summary: Need a better error message - Use of alias in window function definition
Key: DRILL-3243
URL: https://issues.apache.org/jira/browse/DRILL-3243
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Affects Versions: 1.0.0
Reporter: Khurram Faraaz
Assignee: Chris Westin
Need a better error message when we use alias for window definition in query that uses window functions. for example, OVER(PARTITION BY columns[0] ORDER BY columns[1]) tmp, and if alias "tmp" is used in the predicate we need a message that says, column "tmp" does not exist, that is how it is in Postgres 9.3
Postgres 9.3
{code}
postgres=# select count(*) OVER(partition by type order by id) `tmp` from airports where tmp is not null;
ERROR: column "tmp" does not exist
LINE 1: ...ect count(*) OVER(partition by type order by id) `tmp` from ...
^
{code}
Drill 1.0
{code}
0: jdbc:drill:schema=dfs.tmp> select count(*) OVER(partition by columns[2] order by columns[0]) tmp from `airports.csv` where tmp is not null;
Error: SYSTEM ERROR: java.lang.IllegalArgumentException: Selected column(s) must have name 'columns' or must be plain '*'
