The `ORDER BY` clause sort results by specified columns and order.
|
|
Sort data based on fields, tags, and timestamps.
|
|
The following orders are supported:
|
|
|
|
- `ASC`: ascending _(default)_
|
|
- `DESC`: descending
|
|
|
|
- [Syntax](#syntax)
|
|
- [Examples](#examples)
|
|
|
|
## Syntax
|
|
|
|
```sql
|
|
[SELECT CLAUSE] [FROM CLAUSE] [ ORDER BY expression [ ASC | DESC ][, …] ]
|
|
```
|
|
|
|
{{% note %}}
|
|
**Note:** If your query includes a `GROUP BY` clause, the `ORDER BY` clause must appear **after** the `GROUP BY` clause.
|
|
{{% /note %}}
|
|
|
|
## Examples
|
|
|
|
### Sort data by time with the most recent first
|
|
|
|
```sql
|
|
SELECT
|
|
"water_level", "time"
|
|
FROM
|
|
"h2o_feet"
|
|
WHERE
|
|
"location" = 'coyote_creek'
|
|
ORDER BY
|
|
time DESC
|
|
```
|
|
|
|
{{< expand-wrapper >}}
|
|
{{% expand "View example results" %}}
|
|
| time | water_level |

### Sort data by tag or field values
|
|
|
|
```sql
|
|
SELECT
|
|
"water_level", "time", "location"
|
|
FROM
|
|
"h2o_feet"
|
|
ORDER BY
|
|
"location", "water_level" DESC
|
|
```
|
|
|
|
### Sort data by selection order
|
|
|
|
```sql
|
|
SELECT
|
|
"location","water_level", "time"
|
|
FROM
|
|
"h2o_feet"
|
|
ORDER BY
|
|
1, 2
|
|
```
|
|
|
|
{{< expand-wrapper >}}
|
|
{{% expand "View example results" %}}
|
|
The query sorts results the location of a column in the `SELECT` statement:
|
|
first by `location` (1), and second by `water_level` (2).
|
|
|
|
| location | time | water_level |
