Subject [jira] [Created] (FLINK-6562) Support implicit table references for nested fields in SQL
Date Thu, 11 May 2017 21:21:04 GMT
Haohui Mai created FLINK-6562:
---------------------------------

             Summary: Support implicit table references for nested fields in SQL
                 Key: FLINK-6562
                 URL: https://issues.apache.org/jira/browse/FLINK-6562
             Project: Flink
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Currently nested fields can only be accessed through fully qualified identifiers. For example,
users need to specify the following query for the table {{f}} that has a nested field {{foo.bar}}

{noformat}
SELECT f.foo.bar FROM f
{noformat}

Other query engines like Hive / Presto supports implicit table references. For example:

{noformat}
SELECT foo.bar FROM f
{noformat}

This jira proposes to support the latter syntax in the SQL API.
