HIVE-9028: Enhance the hive parser to accept tuples in where in clause
filter
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').... )
Have added support for these queries in spark sql
