mysql 查詢當天、本週，本月，上一個月的數據

今天

select * from 表名 where to_days(時間字段名) = to_days(now());

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1

近7天

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

近30天

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

本月

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

上一月

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

查詢本季度數據

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

查詢上季度數據

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

查詢本年數據

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

查詢上年數據

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

查詢當前這周的數據

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

查詢上週的數據

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

查詢上個月的數據

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  上月最後一天  and 下月第一天

查詢當前月份的數據

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

查詢距離當前如今6個月的數據

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

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')

查詢每週的數據：

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

查詢每個月的數據：

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

查詢每一年的數據：

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

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

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

查出第幾周到第幾周的區間數據:

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 數據表
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);

多表關聯查詢:

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

函數查詢求和:

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

嵌套查詢:

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

多重嵌套查詢:

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)
