I think one of the reason is that the resulting type is a {{GenericType}} instead of a specific {{RowTypeInfo}} which I had some hard time dealing with in FLINK-9294. Another think that might have been related is: FLINK-10019 where there are some issues with Calcite when trying to type inference a {{Struct Type}}. I can dig deeper into this :-) > Access composite type fields after a function > --------------------------------------------- > > Key: FLINK-10273 > URL: https://issues.apache.org/jira/browse/FLINK-10273 > Project: Flink > Issue Type: Bug > Components: Table API & SQL > Affects Versions: 1.7.0 > Reporter: Timo Walther > Priority: Major > > 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} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
