> Tajo supports simple query as the following form:
> {noformat}
> select * from tb1
> {noformat}
> or
> {noformat}
> select * from tb1 LIMIT N
> {noformat}
> In many cases, users want to use some projections or functions like 
> {noformat}
> select x,y,z from tb1 LIMIT N
> {noformat}
> This kind of queries are usually used to just see the data contents. Many users expect that this query will return the result immediately. But, the simple does not support  this case. We need to support it.
