sandeep purohit commented on CARBONDATA-688:
--------------------------------------------
We just create another simple table and filter null values but it is giving
correct result so the reason of bug is not to filter expression we need to
check what is exact reason for this bug
We follow below queries
cc.sql("create table tabled (name String,age double) STORED BY
'org.apache.carbondata.format'")
cc.sql("LOAD DATA INPATH '/home/sandy/try1.csv' INTO table tabled")
cc.sql("select * from tabled").show()
cc.sql("select * from tabled where age IS NOT NULL").show()
cc.sql("select * from tabled where age IS NULL").show()
> Select query displays wrong data for double datatype having null values

> Select query:
> select gamePointId from Comp_VMALL_DICTIONARY_INCLUDE where gamePointId IS
> NOT NULL order by gamePointId;
> select gamePointId from Comp_VMALL_DICTIONARY_INCLUDE where gamePointId is
> NULL;
> The first select command displays null values as well and the second command
> displays no values.
