[jira] [Updated] (CALCITE-2276) Calcite unable to parse ROW value constructor in certain scenario

     [ https://issues.apache.org/jira/browse/CALCITE-2276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Julian Hyde updated CALCITE-2276:
---------------------------------
    Description: 
h2. Original dev mailing list question:

Now for our production, we can parse a query successfully like this :

{code}
-- correlated IN subquery
-- TC 01.01
SELECT t1a,
       t1b,
       t1h
FROM   t1
WHERE  ( t1a, t1h ) NOT IN (SELECT t2a,
                                   t2h
                            FROM   t2
                            WHERE  t2a = t1a
                            ORDER  BY t2a)
AND t1a = 'val1a'
{code}

but if we add in `Row`:

{code}
-- correlated IN subquery
-- TC 01.01
SELECT t1a,
       t1b,
       t1h
FROM   t1
WHERE  ROW( t1a, t1h ) NOT IN (SELECT t2a,
                                   t2h
                            FROM   t2
                            WHERE  t2a = t1a
                            ORDER  BY t2a)
AND t1a = 'val1a'
{code}

 it will throw exception:

{noformat}
Caused by: org.apache.calcite.sql.parser.SqlParseException: ROW expression
encountered in illegal context
  at org.apache.calcite.sql.parser.impl.SqlParserImpl.convertException(SqlParserImpl.java:351)

  at org.apache.flink.table.calcite.FlinkPlannerImpl.parse(FlinkPlannerImpl.scala:81)
... 8 more
{noformat}

For the success query, if we exec parsed AST tree rootNode.toString(), it
will return a query like:

{code}
SELECT `t1a`,
       `t1b`,
       `t1h`
FROM `t1`
WHERE ROW(`t1a`, `t1h`) NOT IN (SELECT `t2a`, `t2h`
                                FROM `t2`
                                WHERE `t2a` = `t1a`
                                ORDER BY `t2a`)
AND `t1a` = 'val1a'
{code}

This is inconsistent  by Calcite itself semantic.
