SQL查询月、天、周、年数据
计算今天是星期几
select datename(weekday,getdate())
查询本年的数据
select * from users where year(time)=year(getdate())
查询本月的数据,time是表users中代表时间的字段
select * from users where month(time)=month(getdate()) and year(time)=year(getdate())
查询今天的数据,time 是表中代表时间的字段
select * from users where day(time)=day(getdate()) and month(time)=month(getdate()) and year(time)=year(getdate())
计算那一天是星期一
SELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 0)
计算那一天是周末
select dateadd(wk,datediff(wk,0,getdate()),6)
查询本周的数据
select * from users where DATEPART(wk, time) = DATEPART(wk, GETDATE()) and DATEPART(yy, time) = DATEPART(yy, GETDATE())
查询本日的记录
select * from users where (DATEDIFF(dd, time, GETDATE()) = 0)
*查询本月的记录
select * from users where (DATEDIFF(mm, time, GETDATE()) = 0)
查询本年的记录
select * from users where (DATEDIFF(yy, time, GETDATE()) = 0)在MySql中实现
本年:
select * from loanInfo where year(date)=year(getdate())
本月:
select * from loanInfo where year(date)=year(getDate()) And month(date)=month(getdate())
本日:
select * from loanInfo where year(date)=year(getDate()) And month(date)=month(getdate()) and Day(date)=Day(getDate())
15SELECT * FROM table WHERE (MONTH(字段) = MONTH(GETDATE()))
