查询某段时间内请求次数排在 TOP N 的 SQL

运行如下语句可以查询某段时间内请求次数排在 TOP N 的 SQL：

SELECT /*+ PARALLEL(15)*/
    SQL_ID, COUNT(*) AS QPS,
    AVG(t1.elapsed_time) RT
FROM oceanbase.GV$OB_SQL_AUDIT t1
WHERE tenant_id = 1001
AND IS_EXECUTOR_RPC = 0
AND request_time > (time_to_usec(now()) - 10000000)
AND request_time < time_to_usec (now())
GROUP BY t1.sql_id
ORDER BY QPS DESC
LIMIT 10;

返回结果如下：

+----------------------------------+------+------------+
| SQL_ID                           | QPS  | RT         |
