> If there is no data, tsql will print as follows:
> {code:xml}
> default> select * from table1;
> id, name, score, type
> -------------------------------
> 1, name1-1, 1.1, a
> 2, name1-2, 2.3, b
> 3, name1-3, 3.4, c
> 4, name1-4, 4.5, d
> 5, name1-5, 5.6, e
> default> select count(*) from table1 where id = 10;
> Progress: 100%, response time: 0.231 sec
> ?count
> -------------------------------
> (0 rows, 0.231 sec, 0 B selected)
> {code}
> But it need to print result detailedly as follows:
> {code:xml}
> ?count
> -------------------------------
> 0
> -------------------------------
> (1 rows, 0.231 sec, 0 B selected)
> {code}
> Because if users implement some applications with TajoClient or TajoJDBC,
> they can't understand easy that a query finished successfully or a query
> finished unsuccessfully.
