Rong Rong commented on FLINK-10273:
-----------------------------------

I was able to reproduce it on SQL but not Table API. See: https://github.com/apache/flink/compare/master...walterddr:test-FLINK-10273
SQL API throws Exception:

{code}
org.apache.flink.table.api.SqlParserException: SQL parse failed. Encountered "." at line 1, column 19.
Was expecting one of:

while Scala Table API is perfectly fine getting the field out. 
[~twalthr] does this match your finding? I can take a quick look, it doesn't seem to be related to FLINK-10019, but seems familiar when we dealt with FLINK-7923.

> If a function returns a composite type, for example, {{Row(lon: Float, lat: Float)}}. There is currently no way of accessing fields.
> Both queries fail with exceptions:
> {code}
> select t.c.lat, t.c.lon FROM (select toCoords(12) as c) AS t
> {code}
> {code}
> select toCoords(12).lat
> {code}
