Date Mon, 25 Jul 2016 14:47:20 GMT
Timo Walther created FLINK-4263:
-----------------------------------

             Summary: SQL's VALUES does not work properly
                 Key: FLINK-4263
                 URL: https://issues.apache.org/jira/browse/FLINK-4263
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
            Reporter: Timo Walther


Executing the following SQL leads to very strange output:

{code}
SELECT  *
FROM    (
        VALUES
        (1, 2),
        (3, 4)
        ) AS q (col1, col2)"
{code}
