Hi Jay,
Yes, Hive parser is stripping out the "as". As Gopal explained in the
earlier thread, parser is used to translate a SQL string into an AST, i.e.,

Hi Rakesh,
If you would like to get all the names starting with r, you can use
select * from emp where name like 'r%';
or
select * from emp where name rlike '^r';
or
select * from emp where name regexp '^r';
Thanks.
