在特定月份中計數條目

Question

我想在一個月內統計我數據庫中表格中的條目。例如1月份的總條目。我試過這個，但它沒有解決。

SELECT MONTH(date1 = '$2015-01-01$') COUNT (*) COUNT from restowlist 
    WHERE MONTH(date1='$2015-01-01$') 

請幫忙。

Answer 1

SELECT 
    COUNT(*) 
FROM 
    restowlist 
WHERE 
    MONTH(yourDateColumn) = 1 AND YEAR(yourDateColumn) = 2015 

Answer 2

select count(*) 
from restowlist 
where month(date1) = 1 
and year(date1) = 2015 

Answer 3

你可以嘗試

SELECT COUNT(*) 
FROM restowlist 
WHERE DATEPART('year', datecolumn) = 2015 
AND DATEPART('month', datecolumn) = 1 

（道歉，因爲我的語法來自SQL，而不是MySQL的）

Answer 4

SELECT COUNT(*) FROM `restowlist` 
WHERE `date1` BETWEEN cast('2016-01-01' as DATE) 
AND cast('2016-01-31' as DATE);
