Julian Hyde commented on DRILL-1726:
------------------------------------
What Tomer wants is reasonable. I don't recall whether the SQL standard allows
access to nested collections, but it should be possible to come up with a
reasonable semantics (e.g. look for table aliases first, then look for columns;
and also look for schemas, because the standard does allow 'select
myschema.emp.name from myschema.emp').
Can you log a Calcite feature request please.
> Query fails when table is not named

> Project: Apache Drill
> Issue Type: Bug
> Reporter: Tomer Shiran

> The first query failed, and the second succeeded. The only difference was
> that the field was referred to with the table name b (ie, b.hours.Friday vs.
> hours.Friday). Both should work.
> {code}
> 0: jdbc:drill:zk=localhost:2181> SELECT name, hours.Friday FROM

> Query failed: Failure while running sql.
> Error: exception while executing query: Failure while executing query.
