在当前日期的下个月或下一年内显示员工周年纪念日期
Display employee anniversary dates within the next month or year of current date
主要是尝试创建一个查询,以显示当前日期下一个月或下一年的员工周年纪念日期,还想显示一个显示服务年限的列
SELECT
Employee,
Hire_Date
CASE WHEN DATEADD(YY,DATEDIFF(yy,Hire_Date,GETDATE()),Hire_Date)<GETDATE() THEN DATEDIFF(yy,Hire_Date,GETDATE())
ELSE DATEDIFF(yy,Hire_Date,GETDATE())-1 END AS 'Years of service'
FROM
MyTable
希望显示下个月或明年即将到来的周年纪念日的员工
这是经过验证的脚本(见下图),用于显示 birth_date 下个月
的员工
把我的table换成你自己的table
declare @mytable as table(employe varchar(100), birth_date datetime,hire_date datetime)
insert into @mytable values
('name1','01/01/1972','01/01/2000') ,
('name2','12/02/1985','01/02/2003') ,
('name3','04/12/1990','03/04/2005') ,
('name4','05/03/1969','12/12/2005') ,
('name5','04/02/1968','12/02/2010') ,
('name6','04/04/1968','12/11/2009') ,
('name7','12/03/1978','01/01/2019') ,
('name8','01/12/2000','03/02/2018') ,
('name9','12/12/1970','05/02/2019') ,
('name10','04/04/1980','04/04/2018')
select employe,birth_date,hire_date,
CASE WHEN DATEADD(YY,DATEDIFF(yy,Hire_Date,GETDATE()),Hire_Date)<GETDATE() THEN DATEDIFF(yy,Hire_Date,GETDATE())
ELSE DATEDIFF(yy,Hire_Date,GETDATE())-1 END AS 'Years of service'
from @mytable where (
month(getdate()) < 12
and
month(birth_date)=1+month(getdate()) )
or (month(getdate())=12 and month(birth_date)=1)
我不太明白,但是,如果你想知道谁在下个月或明年过生日,你应该使用DATEDIFF
函数来过滤数据。
示例:
SELECT Employee, Hire_Date, DATEDIFF(year, Hire_Date, getdate()) as YearsService
FROM MyTable
-- if you need fetch to next month, you should use <= 1
WHERE DATEDIFF(month, CONCAT(YEAR(GETDATE()), '-', MONTH(Hire_Date), '-' , DAY(Hire_Date)), GETDATE()) = 1
