ATTACHMENT ID: 12766876 - PreCommit-HIVE-TRUNK-Build
> Pad Decimal numbers with trailing zeros to the scale of the column
> ------------------------------------------------------------------
>
> Key: HIVE-12063
> URL: https://issues.apache.org/jira/browse/HIVE-12063
> Project: Hive
> Issue Type: Improvement
> Components: Types
> Affects Versions: 0.14.0, 1.0.0, 1.2.0, 1.1.0, 0.13
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Attachments: HIVE-12063.1.patch, HIVE-12063.patch
>
>
> HIVE-7373 was to address the problems of trimming tailing zeros by Hive,
> which caused many problems including treating 0.0, 0.00 and so on as 0, which
> has different precision/scale. Please refer to HIVE-7373 description.
> However, HIVE-7373 was reverted by HIVE-8745 while the underlying problems
> remained. HIVE-11835 was resolved recently to address one of the problems,
> where 0.0, 0.00, and so on cannot be read into decimal(1,1).
> However, HIVE-11835 didn't address the problem of showing as 0 in query
> result for any decimal values such as 0.0, 0.00, etc. This causes confusion
> as 0 and 0.0 have different precision/scale than 0.
> The proposal here is to pad zeros for query result to the type's scale. This
> not only removes the confusion described above, but also aligns with many
> other DBs. Internal decimal number representation doesn't change, however.
