Paul Rogers commented on DRILL-5555:
------------------------------------
Note that the same problem applies to this query as well:
{code}
SELECT *, a FROM `dfs.data`.`example.csv`
{code}
The above produces the same result as described in the ticket description.
Suggestion: do not allow other column references if an unqualified star appears
in the SELECT list.
> CSV file without headers: "SELECT a" fails, "SELECT columns, a" succeeds

> Key: DRILL-5555
> URL: https://issues.apache.org/jira/browse/DRILL-5555
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
> Priority: Minor
>
> Consider the case discussed in DRILL-5554. Do exactly the same setup, but
> with a slightly different query. The results are much different.
> Create a CSV file without headers:
> {code}
> 10,foo,bar
> {code}
> Use a CSV storage plugin configured to not skip the first line and not read
> headers.
> Then, issue the following query:
> {code}
> SELECT columns, a FROM `dfs.data.example.csv`
> {code}
> Result:
> {code}
> columns,a
> ["10","foo","bar"],null
> {code}
> Schema:
> {code}
> columns(VARCHAR:REPEATED),
> a(INT:OPTIONAL)
> {code}
> Since the query in DRILL-5554 fails:
> {code}
> SELECT a FROM ...
> {code}
> Expected the query described here to also fail, for a similar reason.
