Subject [jira] [Created] (HIVE-9028) Enhance the hive parser to accept tuples in where in clause filter
Date Fri, 05 Dec 2014 05:43:12 GMT
Yash Datta created HIVE-9028:
--------------------------------

             Summary: Enhance the hive parser to accept tuples in where in clause filter
                 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').... )
