雅典娜:按比例因子查询耗尽的资源

我运行的查询如下:

SELECT f.*, p.countryName, p.airportName, a.name AS agentName
FROM (
    SELECT 
        f.outboundlegid, 
        f.inboundlegid,
        f.querydatetime,
        cast(f.agent as bigint) as agent,
        cast(f.querydestinationplace as bigint) as querydestinationplace,
        f.queryoutbounddate,
        f.queryinbounddate,
        f.quoteageinminutes,
        f.price
    FROM flights f
    WHERE querydatetime >= '2018-01-02'
    AND querydatetime <= '2019-01-10'
) f
INNER JOIN (
  SELECT airportId, airportName, countryName
  FROM airports
  WHERE countryName IN ('Philippines', 'Indonesia', 'Malaysia', 'Hong Kong', 'Thailand', 'Vietnam')
) p
ON f.querydestinationplace = p.airportId
INNER JOIN agents a
ON f.agent = a.id
ORDER BY f.outboundlegid, f.inboundlegid, f.agent, querydatetime DESC

怎么了?或者我如何优化它?它给了我

在此比例因子下查询耗尽的资源

我有一个航班表,我想查询特定国家的航班
