Request parameters

The following table describes the required and unique parameters of this command.

Parameter	Type	Required	Example	Description
--project	String	Yes	aliyun-test-project	The name of the project.
--logstore	String	Yes	logstore-a	The name of the Logstore.
--from_time	String	Yes	2021-05-28 15:33:00+8:00	The beginning of the time range to query. Specify the value as a UNIX timestamp or in the `"%Y-%m-%d %H:%M:%S<time_zone>"` format. Example: `“2018-01-02 12:12:10+8:00“`.
--to_time	String	Yes	2021-05-28 15:40:00+8:00	The end of the time range to query. Specify the value as a UNIX timestamp or in the `"%Y-%m-%d %H:%M:%S<time_zone>"` format. Example: `“2018-01-02 12:12:10+8:00“`.
--topic	String	No	""	The topic of the logs to query. The default value is double quotation marks (""). For more information, see Topic.
--query	String	No	`level:Information\|select event_id as Key1,COUNT(*) as Key2 group by Key1`	The search statement or query statement. For more information, see Log search overview and Log analysis overview. If you add `set session parallel_sql=true;` to the analytic statement in the value of the query parameter, the Dedicated SQL feature is used. For example, you can set the value to `* \| set session parallel_sql=true; select count() as pv`. Note* If you specify an analytic statement in the value of the query parameter, you must set the line and offset parameters to 0 and use the LIMIT clause to perform a paged query. An analytic statement is an SQL statement. For more information, see Paginate analysis results.
--reverse	Boolean	No	true	Specifies whether to return logs in descending order of log timestamp. The log timestamps are accurate to minutes. true: Logs are returned in descending order of log timestamp. false: Logs are returned in ascending order of log timestamp. This is the default value. Important The reverse parameter only takes effect when the query parameter is set to a search statement. The reverse parameter specifies the order in which returned logs are sorted. If the query parameter is set to a query statement, the reverse parameter is invalid. The order in which returned logs are sorted is specified by the ORDER BY clause in the analytic statement. If you use the default keyword asc in the ORDER BY clause, the logs are sorted in ascending order. If you use the desc keyword in the ORDER BY clause, the logs are sorted in descending order.
--offset	Integer	No	0	The row from which the query starts. This parameter only takes effect when the query parameter is set to a search statement. Default value: 0.
--size	Integer	No	10	The maximum number of logs to return. This parameter only takes effect when the query parameter is set to a search statement. Minimum value: 0. Maximum value: 100. Default value: 100.
--power_sql	Boolean	No	false	Specifies whether to use the Dedicated SQL feature. For more information, see Enable Dedicated SQL. true: The Dedicated SQL feature is used. false: The Standard SQL feature is used. This is the default value. You can use the powerSql or query parameter to specify whether to use the Dedicated SQL feature.
