mysql 查询当天、本周,本月,上一个月的数据

今天

select * from 表名 where to_days(时间字段名) = to_days(now());

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1

近7天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)

近30天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)

本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )

上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 时间字段名, '%Y%m' ) ) =1

查询本季度数据

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());

查询上季度数据

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查询本年数据

select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());

查询上年数据

select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));

查询当前这周的数据

SELECT name,时间字段名FROM enterprise WHERE YEARWEEK(date_format(时间字段名,'%Y-%m-%d')) = YEARWEEK(now());

查询上周的数据

SELECT name,时间字段名FROM enterprise WHERE YEARWEEK(date_format(时间字段名,'%Y-%m-%d')) = YEARWEEK(now())-1;

查询上个月的数据

select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m')

select * from user where DATE_FORMAT(pudate,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ; 

select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now()) 

select * from user where MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * from user where YEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = YEAR(now()) and MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * from user where pudate between  上月最后一天  and 下月第一天 

查询当前月份的数据

select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

查询距离当前现在6个月的数据

select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

查询每天每周每月每年的总数

查询每天的数据:

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

查询每周的数据:

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

查询每月的数据:

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

查询每年的数据:

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

其它:

DATE_ADD(createTime,INTERVAL 1 DAY) 得到指定日期后一天的日期/把1改为任意数字就可以得到后N天的日期

DATE_SUB(createTime,INTERVAL 1 DAY) 得到指定日期前一天的日期/把1改为任意数字就可以得到前N天的日期

声明变量查询:

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

去重选择后返回条数

SELECT COUNT(DISTINCT(id)) from 数据表 WHERE createdDate BETWEEN '2009-08-06 15:53:14' AND '2009-09-01 15:53:14'

查出第几周到第几周的区间数据:

SELECT 
COUNT(DISTINCT(id)) ,
WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1) AS startweek,
WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1) AS endweek
from 数据表
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1);

多表关联查询:

SELECT
COUNT(DISTINCT(account)) as fuNum, 
op.*,
p.*
from 
A o
LEFT JOIN B op
ON o.id = op.id
LEFT JOIN C p
ON op.id = p.id
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1)
AND id = 3

函数查询求和:

SELECT
COUNT(DISTINCT(op.a)) as pa, 
COUNT(p.b) AS sa,
SUM(o.c) AS ta
from 
A o
LEFT JOIN B op
ON o.id = op.id
LEFT JOIN C p
ON op.id = p.id
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1)
AND id = 3

嵌套查询:

SELECT
DISTINCT
(CASE  account
WHEN '0' THEN 'null'
ELSE (SELECT COUNT( DISTINCT(account) ) FROM  eps_order WHERE payStatus = 'paid') END) AS payNum,
COUNT(p.`order`) AS saleOrders,
SUM(o.amount) AS totalAmount
from 
A o
LEFT JOIN B op
ON o.id = op.orderID
LEFT JOIN C p
ON op.productID = p.id
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1)
AND  o.`status` != 'canceled'
AND productID = 3

多重嵌套查询:


SELECT
DISTINCT
(CASE  o.account
WHEN NULL THEN 'null'
ELSE 
(
SELECT 
COUNT( DISTINCT(o.account) ) 
from 
A o
LEFT JOIN B op
ON o.id = op.orderID
LEFT JOIN C p
ON op.productID = p.id
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2009-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2009-08-06 15:53:14','%Y-%m-%d'),1)
AND  o.`status` != 'canceled'
AND productID = 3
) 
END) AS payNum,
COUNT(p.`order`) AS saleOrders,
SUM(o.amount) AS totalAmount
from 
A o
LEFT JOIN B op
ON o.id = op.orderID
LEFT JOIN C p
ON op.productID = p.id
WHERE
 WEEK(date_format(createdDate,'%Y-%m-%d'),1)
BETWEEN
 WEEK(date_format('2018-08-05 15:53:14','%Y-%m-%d'),1)
 AND WEEK(date_format('2018-08-06 15:53:14','%Y-%m-%d'),1)
AND  o.`status` != 'canceled'
AND productID = 3
