php的問題。我用的是mysql，若只顯示今年的數(shù)據(jù)，表里時間格式是0000-00-00,sql語句該怎么寫？

select * from ht_invoice_information where WEEKOFYEAR(create_date)=WEEKOFYEAR(NOW());

#查詢上周記錄

select * from ht_invoice_information where create_date=date_add(now(),interval -(8 + weekday(now())) day)

and create_date=date_add(now(),interval -(1 + weekday(now())) day);

#或者

select * from `ht_invoice_information` where WEEKOFYEAR(create_date)=WEEKOFYEAR(DATE_SUB(now(),INTERVAL 1 week));

#查詢本月數(shù)據(jù)

select * from ht_invoice_information where MONTH(create_date)=MONTH(NOW()) and year(create_date)=year(now());

#查詢上月數(shù)據(jù)

select * from ht_invoice_information where create_date=last_day(date_add(now(),interval -1 MONTH))

and create_date=DATE_FORMAT(concat(extract(year_month from date_add(now(),interval -1 MONTH)),'01'),'%Y-%m-%d');

#或者

select * from `ht_invoice_information` where MONTH(create_date)=MONTH(DATE_SUB(NOW(),interval 1 month))

and year(create_date)=year(now());

#查詢本季度數(shù)據(jù)

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

#查詢上季度數(shù)據(jù)

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

#查詢本年數(shù)據(jù)

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

#查詢上年數(shù)據(jù)

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

參考這個吧，很全了。

怎樣在MySQL中操作日期

select curDate(); #獲取當前日期select curTime(); #獲取當前時間select now(); #獲取當前日期+時間

列舉1個天數(shù)加減的例子，其他的看英文意思就可以理解了

select date_add(now(), interval 1 day); #當前日期天數(shù)+1

select date_add(now(), interval -1 day); #當前日期天數(shù)-1

select date_add(now(), interval 1 hour);

select date_add(now(), interval 1 minute);

select date_add(now(), interval 1 second);

select date_add(now(), interval 1 microsecond);

select date_add(now(), interval 1 week);

select date_add(now(), interval 1 month);

select date_add(now(), interval 1 quarter);

select date_add(now(), interval 1 year);

如何 用mysql語句獲取本季度的第一天 本月

本季度的第一天 ，然后你可以把字符串再轉換為日期。 方法很多，包括同一個函數(shù)的別名（同義詞）也很多。比如CURDATE(),CURRENT_DATE(), CURRENT_DATE, NOW 等都可以返回當天

mysql教程 select CURDATE(),ELT(QUARTER(CURDATE()),

- year(CURDATE())*1000+0101,

- year(CURDATE())*1000+0401,

- year(CURDATE())*1000+0701,

- year(CURDATE())*1000+1001) as firstDayofQ;

+------------+-------------+

| CURDATE() | firstDayofQ |

+------------+-------------+

| 2009-05-19 | 2009401 |

+------------+-------------+

用mysql語句獲取本季度的第一天

本月的第一天，

date(

concat(year(curdate()),'-',month(curdate()),'-','1'))

本周的第一天

curdate()-

WEEKDAY(curdate())

用mysql語句獲取本季度的第一天

mysql 怎么查詢now() 要顯示年份 和季度數(shù)

您好，一、年度查詢

查詢 本年度的數(shù)據(jù)

SELECT *

FROM blog_article

WHERE year( FROM_UNIXTIME( BlogCreateTime ) ) = year( curdate( ))

二、查詢季度數(shù)據(jù)

查詢數(shù)據(jù)附帶季度數(shù)

SELECT ArticleId, quarter( FROM_UNIXTIME( `BlogCreateTime` ) )

FROM `blog_article`

其他的同前面部分：查詢 本季度的數(shù)據(jù)

SELECT *

FROM blog_article

WHERE quarter( FROM_UNIXTIME( BlogCreateTime ) ) = quarter( curdate( ))

三、查詢月度數(shù)據(jù)

本月統(tǒng)計(MySQL)

select * from booking where month(booking_time) =

month(curdate()) and year(booking_time) = year(curdate())

本周統(tǒng)計(MySQL)

select * from spf_booking where month(booking_time) =

month(curdate()) and week(booking_time) = week(curdate())

四、時間段

N天內(nèi)記錄

WHERE TO_DAYS(NOW()) - TO_DAYS(時間字段) = N

當天的記錄

where date(時間字段)=date(now())

或

where to_days(時間字段) = to_days(now());

查詢一周：

select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) = date(column_time);

查詢一個月：

select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) = date(column_time);

查詢'06-03'到'07-08'這個時間段內(nèi)所有過生日的會員：

Select * From user Where

DATE_FORMAT(birthday,'%m-%d') = '06-03' and DATE_FORMAT(birthday,'%m-%d')

= '07-08';

統(tǒng)計一季度數(shù)據(jù)，表時間字段為：savetime

group by concat(date_format(savetime, '%Y '),FLOOR((date_format(savetime, '%m ')+2)/3))

或

select YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1,count(*)

from yourTable

group by YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1;

五、分組查詢

1、年度分組

2、月度分組

3、先按年度分組，再按月度分組

4、按年月分組

SELECT count(ArticleId), date_format(FROM_UNIXTIME( `BlogCreateTime`),'%y%m') sdate FROM `blog_article` group by sdate

結果：

count( ArticleId ) sdate

17 0901

11 0902

5 0903

6 0904

2 0905

1 0907

12 0908

6 0909

11 0910

3 0911

sql--按照季度統(tǒng)計銷售額 怎么寫？

倆方法

select?year(訂單.訂購日期)年份,

sum(case?when?month(訂單.訂購日期)?between?1?and?3?then?訂單明細.單價*訂單明細.數(shù)量?else?0?end)?一季度銷售金額,

sum(case?when?month(訂單.訂購日期)?between?4?and?6?then?訂單明細.單價*訂單明細.數(shù)量?else?0?end)?二季度銷售金額,

sum(case?when?month(訂單.訂購日期)?between?7?and?9?then?訂單明細.單價*訂單明細.數(shù)量?else?0?end)?三季度銷售金額,

sum(case?when?month(訂單.訂購日期)?between?10?and?12?then?訂單明細.單價*訂單明細.數(shù)量?else?0?end)?四季度銷售金額

from?訂單,訂單明細?

where?訂單.訂單ID=訂單明細.訂單ID?and?year(訂單.訂購日期)?between?1996?and?1998

group?by?year(訂單.訂購日期)

select?year(訂單.訂購日期)?年份,

case?when?month(訂單.訂購日期)?between?1?and?3?then?'一季度'

when?month(訂單.訂購日期)?between?4?and?6?then?'二季度'

when?month(訂單.訂購日期)?between?7?and?9?then?'三季度'

when?month(訂單.訂購日期)?between?10?and?12?then?'四季度'?end?季度,

sum(訂單明細.單價*訂單明細.數(shù)量)?金額

from?訂單,訂單明細?

where?訂單.訂單ID=訂單明細.訂單ID?and?year(訂單.訂購日期)?between?1996?and?1998

group?by?year(訂單.訂購日期),

case?when?month(訂單.訂購日期)?between?1?and?3?then?'一季度'

when?month(訂單.訂購日期)?between?4?and?6?then?'二季度'

when?month(訂單.訂購日期)?between?7?and?9?then?'三季度'

when?month(訂單.訂購日期)?between?10?and?12?then?'四季度'?end
