ah, thanks Erek.
I can easily handle this in where clause.
Thanks much.

select blah
from table a
Left Join table b *on (a.col1 = b.col2)*
*where b.col2 is not null or a.col1 = 0*

How do you join two tables that aren't represented in both sides of the =?
Can you describe a bit more of what you are trying to get out of the data?
I am having a hard time wrapping my head around this...

Hi All,
I am joining 2 tables in hive, with or condition. for example:
select blah
from table a
Join table b
*on (a.col1 = b.col2 or a.col2 = 0)*
*
*
but this is giving me error that OR not supported in hive currently.
Any suggestion how I can handle this in hive query.
Thanks,
Sonia
