Jaehwa Jung updated TAJO-840:
-----------------------------
Description:
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.
