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 '*' Fragment 0:0 [Error Id: 66987b81-fe50-422d-95e4-9ce61c873584 on centos-02.qa.lab:31010] (state=,code=0) {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
