Alan Gates commented on HIVE-4214: ---------------------------------- When the query is re-written to properly put the / 10.0 after the OVER, it fails with: {code} NoViableAltException(15@[129:7: ( ( ( KW_AS )? identifier ) | ( KW_AS LPAREN identifier ( COMMA identifier )* RPAREN ) )?]) {code} > OVER accepts general expression instead of just function > -------------------------------------------------------- > > Key: HIVE-4214 > URL: https://issues.apache.org/jira/browse/HIVE-4214 > Project: Hive > Issue Type: Bug > Components: PTF-Windowing > Affects Versions: 0.11.0 > Reporter: Alan Gates > > The query: > select s, i, avg(d) / 10.0 over (partition by s order by i) from over100k; > runs (and produces meaningless output). > Over should not allow the arithmetic expression. Only a UDAF or PTF function > should be valid there. The correct way to write this query should be > select s, i, avg(d) over (partition by s order by i) / 10. 0 from over100k; -- This message is automatically generated by JIRA.
