ATTACHMENT ID: 12699980 - PreCommit-HIVE-TRUNK-Build > Build UDF TRUNC to implement FIRST_DAY as compared with LAST_DAY > ---------------------------------------------------------------- > > Key: HIVE-9480 > URL: https://issues.apache.org/jira/browse/HIVE-9480 > Project: Hive > Issue Type: Bug > Components: UDF > Affects Versions: 0.14.0 > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Attachments: HIVE-9480.1.patch, HIVE-9480.3.patch, HIVE-9480.4.patch, > HIVE-9480.5.patch, HIVE-9480.6.patch > > > Hive already supports LAST_DAY UDF, in some cases, FIRST_DAY is necessary to > do date/timestamp related computation. This JIRA is to track such an > implementation. Choose to impl TRUNC, a more standard way to get the first > day of a a month, e.g., SELECT TRUNC('2009-12-12', 'MM'); will return > 2009-12-01, SELECT TRUNC('2009-12-12', 'YEAR'); will return 2009-01-01. > BTW, this TRUNC is not as feature complete as aligned with Oracle one. only > 'MM' and 'YEAR' are supported as format, however, it's a base to add on other > formats. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
