[jira] [Updated] (FLINK-8003) Support Calcite's ROW value constructor in Flink SQL

["Shuyi Chen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-8003?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shuyi Chen updated FLINK-8003:
------------------------------
    Description: 
We want to use the row value constructor and CAST to create a named row, or even nested named row, e.g.

{code:java}
CREATE TYPE myrowtype AS (f1 INTEGER, f2 VARCHAR(10))
SELECT CAST(ROW(intField, "test") AS myrowtype) AS myRow FROM myTable;
{code}

So if converted to JSON, the output will be {"myRow":{"f0": ${intField}, "f1":"test"}}.
