mysql查询时间_mysql日期查询

-- 本月第一天
select date_add(curdate(),interval-day(curdate())+1 day) as date
-- 本月最后一天
select last_day(curdate()) as date
-- 查询今天的日期 
select CURDATE() as '当前日期';
-- 查询当前时间
select NOW() as '当前时间';
-- 明天日期
select DATE_SUB(curdate(),INTERVAL -1 DAY) AS tomorrow 
-- 下个月第一天
select date_add(curdate() - day(curdate()) +1,interval 1 month )
-- 当前月已过几天
select day(curdate())
-- 当前月天数
select day(date_add( date_add(curdate(),interval 1 month),interval -day(curdate()) day ))
 
-- 最近7天日期
SELECT @s :=@s + 1 as `index`, DATE(DATE_ADD(CURRENT_DATE, INTERVAL @s DAY)) AS `date`
FROM mysql.help_topic,(SELECT @s := -7) temp
WHERE @s < 0
ORDER BY 'date'
 
-- 当天以后7天日期
SELECT @s :=@s + 1 as `index`, DATE(DATE_SUB(CURRENT_DATE, INTERVAL @s DAY)) AS `date`
FROM mysql.help_topic,(SELECT @s := -7) temp
WHERE @s < 0
ORDER BY 'date'
 
一、查询本周日期
SELECT @a :=@a + 1 as `index`, DATE(ADDDATE(CURRENT_DATE, INTERVAL @a DAY)) AS `date`
FROM mysql.help_topic,(SELECT @a := 0) temp
WHERE @a < 6 - WEEKDAY(CURRENT_DATE)
UNION
SELECT @s :=@s - 1 as `index`, DATE(DATE_SUB(CURRENT_DATE, INTERVAL @s DAY)) AS `date`
FROM mysql.help_topic,(SELECT @s := WEEKDAY(CURRENT_DATE) + 1) temp
WHERE @s > 0
ORDER BY `date`
 
二、查询当月所有日期
select date from (
SELECT DATE_FORMAT(DATE_SUB(last_day(curdate()), INTERVAL xc-1 day), '%Y-%m-%d') as date
FROM ( 
			SELECT @xi:=@xi+1 as xc from 
			(SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6) xc1, 
			(SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6) xc2,  
			(SELECT @xi:=0) xc0 
) xcxc) x0 where x0.date >= (select date_add(curdate(),interval-day(curdate())+1 day))
ORDER BY `date`
 
三、查询往后一个月日期
SET @days = TIMESTAMPDIFF( DAY, ADDDATE( date( now( ) ),- 31 ), now( ) );
SET @d = - 1;
SELECT
	@d := @d + 1 AS 'index',
	ADDDATE( ADDDATE( date( now( ) ),- 0), @d ) AS date
FROM
	(
	SELECT a 
	FROM
		( SELECT '1' AS a UNION SELECT '2' UNION SELECT '3' UNION SELECT '4' UNION SELECT '5' UNION SELECT '6' ) AS a
		JOIN ( SELECT '1' UNION SELECT '2' UNION SELECT '3' UNION SELECT '4' UNION SELECT '5' UNION SELECT '6' ) AS b ON 1 
		LIMIT 31 
	) d 
WHERE @d < @days
 
四、查询本年时间，按月份格式返回
select concat((select year(NOW())), '-01') tj_date
union select concat((select year(NOW())), '-02') tj_date
union select concat((select year(NOW())), '-03') tj_date
union select concat((select year(NOW())), '-04') tj_date
union select concat((select year(NOW())), '-05') tj_date
union select concat((select year(NOW())), '-06') tj_date
union select concat((select year(NOW())), '-07') tj_date
union select concat((select year(NOW())), '-08') tj_date
union select concat((select year(NOW())), '-09') tj_date
union select concat((select year(NOW())), '-10') tj_date
union select concat((select year(NOW())), '-11') tj_date
union select concat((select year(NOW())), '-12') tj_date
 
五、查询近一年时间，按日期格式返回
SELECT DATE_SUB(CURDATE(), INTERVAL dummy DAY) AS date
FROM
  (SELECT @rownum:=@rownum+1 AS dummy
   FROM information_schema.tables
   JOIN (SELECT @rownum:=0) r
   LIMIT 365) dates;
 
六、查询去年时间，按月份格式返回
select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-01')  tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-02') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-03') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-04') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-05') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-06') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-07') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-08') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-09') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-10') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-11') tj_date
union select concat((select year(DATE_SUB(NOW(), INTERVAL 1 YEAR))), '-12') tj_date
 
七、查询近6个月时间，按月份格式返回
select date_format(CURDATE(), '%Y-%m') AS tj_date
union select date_format((CURDATE() - INTERVAL 1 MONTH), '%Y-%m') as tj_date
union select date_format((CURDATE() - INTERVAL 2 MONTH), '%Y-%m') as tj_date
union select date_format((CURDATE() - INTERVAL 3 MONTH), '%Y-%m') as tj_date
union select date_format((CURDATE() - INTERVAL 4 MONTH), '%Y-%m') as tj_date
union select date_format((CURDATE() - INTERVAL 5 MONTH), '%Y-%m') as tj_date
