查詢天天每週每個月每一年的總數

查詢天天的數據：

SELECT
	COUNT(1) AS countNumber,
	DATE_FORMAT(createTime,'%Y-%m-%d') AS dateTime
FROM
	testTable
GROUP BY DATE_FORMAT(createTime,'%Y-%m-%d')
複製代碼

查詢每週的數據：

SELECT
	COUNT(1) AS countNumber,
	WEEK(createTime) as dateTime
FROM
	testTable
GROUP BY WEEK(createTime) 
複製代碼

查詢每個月的數據：

SELECT
	COUNT(1) AS countNumber,
	MONTH(createTime) as dateTime
FROM
	testTable
GROUP BY MONTH(createTime)
複製代碼

查詢每一年的數據：

SELECT
	COUNT(1) AS countNumber,
	YEAR(createTime) as dateTime
FROM
	testTable
GROUP BY YEAR(createTime)
複製代碼

其它：

DATE_ADD(createTime,INTERVAL 1 DAY) 獲得指定日期後一天的日期/把1改成任意數字就能夠獲得後N天的日期

DATE_SUB(createTime,INTERVAL 1 DAY) 獲得指定日期前一天的日期/把1改成任意數字就能夠獲得前N天的日期

聲明變量查詢：

SET @counter=0; select @counter:=@counter+1 as id,count(*) as num FROM testTable ORDER BY num desc

去重選擇後返回條數
