如何獲得過去 7 天內每小時的條目數？
[英]How do I get number of entries per hour by the last 7 days?
問題描述
我正在為 MySQL 中的某個查詢而苦苦掙扎。 我真的嘗試了一切！ 如果有人為我指明正確的方向，我將永遠感激不盡。 我的目標是生成一個查詢，顯示過去 7 天每小時的請求數。 我遇到的問題之一是顯示日期的名稱，而不管該日期是否已存在於數據庫中。 換句話說，我希望星期日、星期一、星期二、星期三、星期四、星期五和星期六已經在那里，如果特定日期沒有數據，則像示例中那樣顯示 0。 我希望查詢的輸出如下所示：
我希望查詢輸出的示例
我試過這個：
SELECT
HOUR(`VISIT_TIME`),
COUNT(*)
FROM
`JURL_Analytics`
WHERE
`VISIT_TIME` >= DATE(NOW()) - INTERVAL 7 DAY AND `URL_ID` = 'westonsupermare'
GROUP BY
HOUR(`VISIT_TIME`);
這是數據庫結構的示例
`VISIT_ID`, `VISIT_TIME`
