SELECT
	* 
FROM
	log 
WHERE
	YEARWEEK(
		DATE_FORMAT( AddTime, '%Y-%m-%d' )) = YEARWEEK(
	NOW());

3、 查詢近7天的數據,不包括當天

SELECT
	* 
FROM
	log 
WHERE
	TO_DAYS ( NOW( ) ) - TO_DAYS( AddTime ) <= '7' AND TO_DAYS ( NOW( ) ) - TO_DAYS( AddTime ) > 0;

4、 查詢上周的數據

SELECT
	* 
FROM
	log 
WHERE
	YEARWEEK(
		date_format( AddTime, '%Y-%m-%d' )) = YEARWEEK(

-- 或
SELECT

WHERE

6、查詢上個月的數據

WHERE
	date_format( AddTime, '%Y-%m' )= date_format( DATE_SUB( curdate(), INTERVAL 1 MONTH ), '%Y-%m' );

7、查詢近30天的數據

SELECT
	* 
FROM
	log 
WHERE
	DATE_SUB( CURDATE(), INTERVAL 30 DAY ) <= DATE( AddTime );

8、查詢本季度的數據

	QUARTER ( AddTime ) = QUARTER (
	NOW());
