如果一个国家的面积超过300万平方公里,或者人口超过2500万,那么这个国家就是大国家。
编写一个SQL查询,输出表中所有大国家的名称、人口和面积。
例如,根据上表,我们应该输出:
+--------------+-------------+--------------+ | name | population | area | +--------------+-------------+--------------+ | Afghanistan | 25500100 | 652230 | | Algeria | 37100000 | 2381741 | +--------------+-------------+--------------+
select name,population,area from World where area>3000000 or population>25000000
