Subject [jira] Commented: (HIVE-65) Implict conversion from integer to long broken for Dynamic Serde tables
Date Thu, 04 Dec 2008 00:53:44 GMT

    [ https://issues.apache.org/jira/browse/HIVE-65?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12653090#action_12653090
] 

Zheng Shao commented on HIVE-65:
--------------------------------

@joydeep: There are 2 drawbacks:

1. Authors of udf need to be aware of that.  In oracle, the system does take care of double
-> string in udf so authors don't have to do it.
2. string -> int is lossy. The result of '1.1' = 1 will be true under our agreed conversion
partial order (string -> byte -> short -> int -> ... -> double). But both mysql
and oracle output that as FALSE.

> 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.
