IN clause usage in "where"

Is there a way I can use the "in" list of values in a query condition like 
"select col1 from table1 where col1 in ('abc','xyz')"?

I use Hive 0.6.

Regards,
Karthik.

find_in_set is documented on this page:

http://wiki.apache.org/hadoop/Hive/LanguageManual/UDF

But Hive 0.6 also supports the IN syntax (HIVE-801).

Neil,

Thanks a lot, that works like a charm.  Perhaps, that should go into the Hive Wiki page too sometime.

you can try find_in_set(string str, string strList) , ex.

select col1 from table1 where find_in_set(col1, 'abc,xyz')<>0;

if col1 has NULL values, it can be modified as

select col1 from table1 where find_in_set( coalesce(col1,'') , 'abc,xyz')<>0;

the details about find_in_set are at https://issues.apache.org/jira/browse/HIVE-688
