Subject [jira] [Commented] (FLINK-8003) Support Calcite's ROW value constructor in Flink SQL
Date Wed, 08 Nov 2017 23:35:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16244937#comment-16244937

Shuyi Chen commented on FLINK-8003:

We want to use the row value constructor and CAST to create a named row, or even nested named
row, e.g.

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

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