What should be the sql request statement for a non-roll up dataset

[advanceofta]

I have a time column and a value column, how do I create a dataset with a sql query?
The data table looks like this
+----------+--------+
| time | sales |
+----------+--------+
| 10:00:10 | 2.6304 |
| 10:00:20 | 2.4892 |
| 10:00:30 | 2.5548 |
| 10:00:40 | 2.5891 |
| 10:00:50 | 2.4312 |
| 10:01:00 | 2.6564 |
| 10:01:10 | 2.5427 |
| 10:01:20 | 2.4479 |
