No

Boolean

Parameter description:

Whether a SQL analysis statement contains the pipe character. If this parameter is set to true, the query is performed based on the query parameter in the body, and parameters except start_time and end_time in the body are invalid. Functions such as pagination, sorting, and number of query results are implemented based on the SQL syntax rules.

The response body of the query result is different from that when the pipe character function is disabled. The query result is returned in the default column-store mode. Currently, this function is available only to internal test users.

Example response: {"analysisLogs":[{"field1":"1","field2":"2","field3":"3"},{"field1":"1","field2":"2","field3":"3"},{"field1":"1","field2":"2","field3":"3"}]} (The pipe character function is in the closed test phase. The default value of this parameter is false for non-whitelisted users.)
