Xuefu Zhang reassigned HIVE-5022: --------------------------------- Assignee: Xuefu Zhang (was: Teddy Choi) > Decimal Arithmetic generates NULL value > --------------------------------------- > > Key: HIVE-5022 > URL: https://issues.apache.org/jira/browse/HIVE-5022 > Project: Hive > Issue Type: Bug > Components: Types > Affects Versions: 0.11.0 > Environment: Hortonworks 1.3 running Hive 0.11.0.1.3.0.0-107 > Reporter: Kevin Soo Hoo > Assignee: Xuefu Zhang > Attachments: HIVE-5022.1.patch.txt, HIVE-5022.2.patch.txt, > HIVE-5022.3.patch.txt > > > When a decimal division is the first operation, the quotient cannot be > multiplied in a subsequent calculation. Instead, a NULL is returned. > The following yield NULL results: > select (cast (4.53 as decimal) / cast(25.86 as decimal)) * cast(0.087 as > decimal) from <tablename> limit 1; > select cast (4.53 as decimal) / cast(25.86 as decimal) * cast(0.087 as > decimal) from <tablename> limit 1; > If we move the multiplication operation to be first, then it will > successfully calculate the result. -- This message was sent by Atlassian JIRA (v6.1#6144)
