The ORDER BY syntax is used to sort analysis results by a specified column name.
Syntax Format
ORDER BY column name [DESC | ASC]
Note:
You can specify multiple column names to sort analysis results in different sorting modes, for example, ORDER BY column name 1[DESC | ASC], column name 2[DESC | ASC].
If you do not specify the keyword DESC or ASC, the system sorts the analysis results in ascending order.
If the target column for sorting contains duplicated values, the sorting result may be different each time. If you want the sorting result to remain the same in each sorting, you can specify multiple columns for sorting.
Parameter descriptions:
|
| The column name refers to a log field name or an aggregate function calculation result column. |
| Sort data in descending order. |
| Sort data in ascending order. |
