>
> Key: HIVE-9028
> URL: https://issues.apache.org/jira/browse/HIVE-9028
> Project: Hive
> Issue Type: Improvement
> Components: Parser
> Affects Versions: 0.13.1
> Reporter: Yash Datta
> Fix For: 0.14.0
>
>
> Currently, the hive parser will only accept a list of values in the where in
> clause and the filter is applied only on a single column. Enhanced it to
> accept filter on multiple columns.
> So current support is for queries like :
> Select * from table where c1 in (value1,value2,...value n);
> Added support in the parser for queries like :
> Select * from table where (c1,c2,... cn) in ((value1,value2...value n),
> (value1' , value2' ... ,value n').... )
