Subject [jira] Commented: (HIVE-65) Implict conversion from integer to long broken for Dynamic Serde tables
Date Mon, 17 Nov 2008 18:29:44 GMT

    [ https://issues.apache.org/jira/browse/HIVE-65?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12648230#action_12648230
] 

Ashish Thusoo commented on HIVE-65:
-----------------------------------

Test case is as follows:

CREATE TABLE implicit_test1(a BIGINT, b STRING) ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.dynamic_type.DynamicSerDe'
WITH SERDEPROPERTIES('serialization.format'= 'org.apache.hadoop.hive.serde2.thrift.TCTLSeparatedProtocol')
STORED AS TEXTFILE;


SELECT implicit_test1.*
FROM implicit_test1
WHERE implicit_test1.a <> 0;


Fails to do implicit conversion in the predicate implicit_test1.a <> 0

> For a dynamic serde table that has a bigint column, implict conversion from int to bigint
seems to be broken. I have not verified this for other tables.
