Subject [jira] [Commented] (HIVE-16646) Alias in transform ... as clause shouldn't be case sensitive
Date Thu, 11 May 2017 13:25:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16006394#comment-16006394
] 

Yibing Shi commented on HIVE-16646:
-----------------------------------

Another query that can show this problem more clearly is:
{code:sql}
select t.col from ( 
    select transform(col) using 'cat' as (COL string) from transform3_t1
) t;
{code}

It fails with below error:
{noformat}
FAILED: SemanticException [Error 10002]: Line 1:9 Invalid column reference 'col'
{noformat}

Changing {{as (COL string)}} to {{as (col string)}} makes the query run properly.
