[jira] [Updated] (FLINK-18673) Calling ROW() in a UDF results in
UnsupportedOperationException
[ https://issues.apache.org/jira/browse/FLINK-18673?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fabian Hueske updated FLINK-18673:
----------------------------------
Description:
Given a UDF {{func}} that accepts a {{ROW(INT, STRING)}} as parameter, it cannot be called like this:
{code:java}
SELECT func(ROW(a, b)) FROM t{code}
while this works
{code:java}
SELECT func(r) FROM (SELECT ROW(a, b) FROM t){code}
The exception returned is:
{quote}org.apache.flink.table.api.ValidationException: SQL validation failed. null
{quote}
with an empty {{UnsupportedOperationException}} as cause.
