Sergey Shelukhin commented on HIVE-13098:
-----------------------------------------
This is especially problematic for implicit conversions...
> Add a strict check for when the decimal gets converted to null due to
> insufficient width

> When e.g. 999999 is selected as decimal(5,0), the result is null. This can be
> problematic, esp. if the data is written to a table and lost without the user
> realizing it. There should be an option to error out in such cases instead;
> it should probably be on by default and the error message should instruct the
> user on how to disable it.
