從上個月SQL

Question

選擇數據我有這樣的代碼從我的數據庫中的數據，從本月中進行選擇：

SELECT * FROM daily_reports 
WHERE username = '$username' and MONTH(date) = MONTH(Now()) 
order by date DESC 

，現在我想從上個月顯示數據。

列日期型日期

Answer 1

這應該工作： -

SELECT * 
FROM daily_reports 
WHERE username = '$username' 
and MONTH(date) = MONTH(DATE_ADD(Now(), INTERVAL -1 MONTH)) 
order by date DESC 

Answer 2

SELECT 
    * 
FROM 
    daily_reports 
WHERE username = '$username' 
    AND dateColumn BETWEEN SUBDATE(CURDATE(), INTERVAL 1 MONTH) AND NOW(); 
ORDER BY DATE DESC 

Answer 3

試試這個

SELECT * FROM daily_reports 
WHERE username = '$username' 
and MONTH(date) = MONTH(DATE_ADD(Now(), INTERVAL -1 MONTH)) order by date DESC 

Answer 4

您可以在日期完成許多操作，如圖所示罰款手冊。

在你的情況，也許DATE_SUB function將是清楚的：

SELECT * FROM daily_reports 
WHERE username = '$username' AND MONTH(date) = MONTH(DATE_SUB(Now(), INTERVAL 1 MONTH) 
ORDER BY date DESC 

Answer 5

date BETWEEN date_format 
(NOW() - INTERVAL 1 MONTH, '%Y-%m-01') 
AND last_day(NOW() - INTERVAL 1 MONTH)
