count函数如何进行聚合
使用count函数进行聚合的正确用法如下:
SELECT http_method, count(http_method) FROM apigateway WHERE service_id = 'ecs' Group BY http_method
或者
SELECT http_method FROM apigateway WHERE service_id = 'ecs' DISTRIBUTE BY http_method
错误用法:将会报错。
SELECT http_method, count(http_method) FROM apigateway WHERE service_id = 'ecs' DISTRIBUTE BY http_method
