我需要得到獨特的計數與國家數和總速率以及對每一位用戶的Mysql得到統計數據庫的多個罪名
我想出了數據庫這一基本設計,其中uid
是用戶ID
DROP TABLE IF EXISTS `stats`;
CREATE TABLE IF NOT EXISTS `stats` (
`id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`uid` int(5) UNSIGNED NOT NULL,
`country` int(3) UNSIGNED NOT NULL,
`ip` int(10) UNSIGNED NOT NULL,
`date` int(10) UNSIGNED NOT NULL,
`timestamp` int(10) UNSIGNED NOT NULL,
`rate` int(10) UNSIGNED NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
INSERT INTO `stats`
(`id`, `uid`, `country`, `ip`, `date`, `timestamp`, `rate`) VALUES
(1, 1, 10, 1111111111, 2222222222, 3333333333, 100),
(2, 1, 10, 1111111112, 2222222222, 3333333333, 100),
(3, 2, 10, 1111111111, 2222222222, 3333333333, 100),
(4, 1, 10, 1111111114, 2222222223, 3333333333, 100),
(5, 1, 11, 1111111112, 2222222223, 3333333333, 100),
(6, 1, 10, 1111111111, 2222222223, 3333333333, 100);
這是我使用的日常讀取查詢計數
$query="
SELECT `uid`,
COUNT(DISTINCT `ip`)AS `count`,
`country`,
SUM(`rate`) AS `sum`,
`date`
FROM `stats`
GROUP BY `uid`, `date`
";
$result=mysqli_query($connection, $query) or trigger_error(mysqli_error($connection), E_USER_ERROR);
while($row = mysqli_fetch_assoc($result)){
echo 'userid:'.$row['uid'].' count:'.$row['count'].' country:'.$row['country'].' sum:'.$row['sum'].' date:'.$row['date'].'<br>';
};
我得到這個結果
userid:1 count:2 country:10 sum:200 date:2222222222
userid:1 count:3 country:10 sum:300 date:2222222223
userid:2 count:1 country:10 sum:100 date:2222222222
預期結果
userid:1 count:2 country:10=>2 sum:200 date:2222222222
userid:1 count:3 country:10=>2, 11=>1 sum:300 date:2222222223
userid:2 count:1 country:10=>1 sum:100 date:2222222222
我想我需要這樣的東西SELECT DISTINCT country FROM stats
獲得國家計數主查詢。
請參閱並提出任何可能的方式來做到這一點。
感謝
你也想統計不同的國家嗎? – Strawberry
@Strawberry是的,但結果應該顯示在單行來回一天的任何用戶 –
你怎麼知道哪個日期對應而導致 – Strawberry
