我如何获取 SQLite 查询中过滤的项目的百分比

Question

我正在尝试制作一个 grafana 时间序列图表，显示 pihole 阻止的查询的百分比。我所做的查询如下，但结果肯定不正确，我认为这是因为我处理 where 子句的方式。

SELECT 
  timestamp as time,
  100.0 * (SELECT COUNT( * ) as query_count FROM queries WHERE status IN (1, 4, 5, 6, 7, 8, 9, 10, 11, 15)) / COUNT( * ) as percentage
FROM 
  queries
GROUP BY
  time;

Answer 1

我将其添加到 ypur 查询中：

 Select
 timestamp as time,
(  100.0 * 
(
SELECT COUNT( * ) as query_count FROM queries WHERE status IN (1, 4, 5, 6, 7, 8, 9, 10, 11, 15)
) ) / (SELECT COUNT( * ) as query_count FROM queries) as percentage
FROM 
  queries
GROUP BY
  time;

我在开始时添加选择，并在子查询上添加选择以进行计数
