Subject [jira] Commented: (HIVE-65) Implict conversion from integer to long broken for Dynamic Serde tables
Date Tue, 02 Dec 2008 10:32:44 GMT

    [ https://issues.apache.org/jira/browse/HIVE-65?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12652332#action_12652332
] 

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

> a) evaluate(string, string, int)
> b) evaluate(int, string, string)

This problem even happens for strict-typed languages (replace string with double). So I don't
think this is something we need to fix.


If we agree in most cases people convert string -> numeric, then all numeric->string
can be done by udf itself through polymorphism.
I think this is much cleaner than circular conversion.

I am +1 to stick to the original solution (and leave the author of concat to implement Number->String
conversion).

> 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.
