Rong Rong 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:sql}
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
{code:json}
{"myRow":{"f0": ${intField}, "f1":"test"}}
{code}.
