MYSQL查询语句问题 查询当月和上一月的查询语句怎么写？

select

*

from

shipmentlist,shipmentscrib

where

(shipmentlist.shipmentlistno=shipmentscrib.shipmentlistno)

and (year(shipmentlist.shipmentdate)=year(now()))

and (month(shipmentlist.shipmentdate)=month(now())

or month(shipmentlist.shipmentdate)=month(now())-1 )

ORDER BY shipmentdate DESC

格式化了一下你的SQL，分析一下。

假如今天是 2012年1月1日。

那么上面的条件。

将变为

year = 2012 and month = 1 OR month = 0

其实，对于 查询 当月和上一月

相当于

shipmentlist.shipmentdate >= 上月的1号

AND shipmentlist.shipmentdate <下月的1号

LAST_DAY(NOW()) 可以获取 本月的最后一天.

DATE_ADD( LAST_DAY(NOW()) INTERVAL 1 DAY ) 可以获取下月第一天。

DATE_SUB ( DATE_ADD( LAST_DAY(NOW()) INTERVAL 1 DAY ) INTERVAL 2 MONTH ) 可以获取上月的1号

（也就是用 下月的1号 减少2个月，从而获取 上月的1号）

最后 SQL 修改为：

select

*

from

shipmentlist,shipmentscrib

where

(shipmentlist.shipmentlistno=shipmentscrib.shipmentlistno)

and shipmentlist.shipmentdate >= DATE_SUB ( DATE_ADD( LAST_DAY(NOW()) INTERVAL 1 DAY ) INTERVAL 2 MONTH )

AND shipmentlist.shipmentdate <DATE_ADD( LAST_DAY(NOW()) INTERVAL 1 DAY )

ORDER BY shipmentdate DESC

mysql中怎么查询一周内，三个月内\x0d\x0a使用sql语句查询日期在一周内的数据\x0d\x0aselect * from ShopOrder where datediff(week,ordTime,getdate()-1)=0 //查询当天日期在一周年的数据\x0d\x0aselect * from ShopOrder where datediff(day,ordTime,getdate()-1)=0 //查询当天的所有数据\x0d\x0a SELECT * FROM A where datediff(d,datetime,getdate()) 回答于 2022-12-11

select *

from table_name t1

inner jon table_name t2

on t1.id = t2.id

and t2.日期= 当月日期

where t1.日期 = 上月日期
