Xuefu Zhang updated HIVE-12063: ------------------------------- Attachment: HIVE-12063.2.patch > 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-12063.2.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
