| You may want to run more queries without entering tsql prompt. Tsql provides the ``-c`` argument for above requirement. And Tajo assumes that queries are separated by semicolon as follows: |
| |
| .. code-block:: sql |
| |
| $ bin/tsql -c "select count(*) from table1; select sum(score) from table1;" |
| Progress: 0%, response time: 0.217 sec |
| Progress: 0%, response time: 0.218 sec |
| Progress: 100%, response time: 0.317 sec |
| ?count |
| ------------------------------- |
| 5 |
| (1 rows, 0.317 sec, 2 B selected) |
| Progress: 0%, response time: 0.202 sec |
| Progress: 0%, response time: 0.204 sec |
| Progress: 100%, response time: 0.345 sec |
| ?sum |
| ------------------------------- |
| 15.0 |
| (1 rows, 0.345 sec, 5 B selected) |
