Aitozi commented on FLINK-18027: -------------------------------- [~libenchao] do you know why the explicit ROW construct is removed from the doc, (the git history of the file seems not trackable) Does it's not encouraged to use explicit ROW call ? If not, I think we should add it back. > ROW value constructor cannot deal with complex expressions > ---------------------------------------------------------- > > Key: FLINK-18027 > URL: https://issues.apache.org/jira/browse/FLINK-18027 > Project: Flink > Issue Type: Bug > Components: Table SQL / API > Reporter: Benchao Li > Priority: Not a Priority > Labels: auto-deprioritized-major, auto-deprioritized-minor, > pull-request-available > > {code:java} > create table my_source ( > my_row row<a int, b int, c int> > ) with (...); > create table my_sink ( > my_row row<a int, b int> > ) with (...); > insert into my_sink > select ROW(my_row.a, my_row.b) > from my_source;{code} > will throw excepions: > {code:java} > Exception in thread "main" org.apache.flink.table.api.SqlParserException: SQL > parse failed.
