SQL server 2012 如何取上个月的最后一天

好吧 QQ群里被问到这种问题，还是这里写一下吧。

DECLARE
@date
DATETIME
=
getdate();

SELECT
EOMONTH
(@date)
AS
'Last Day Of This Month',

EOMONTH
(@date, 1)
AS
'Last Day Of Next Month',

EOMONTH
(@date,
-1)
AS
'Last Day Of Previous Month',

EOMONTH
(@date,
-2)
AS
'LAST Last Day Of Previous Month'

     ;

特殊的29日也可以哦
DECLARE
@date
DATETIME
=
'2000-03-01';

SELECT
EOMONTH
(@date)
AS
'Last Day Of This Month',

EOMONTH
(@date, 1)
AS
'Last Day Of Next Month',

EOMONTH
(@date,
-1)
AS
'Last Day Of Previous Month',

EOMONTH
(@date,
-2)
AS
'LAST Last Day Of Previous Month'

     ;

 

其实一个很闲的印度老外已经Code Prject 上写了给很全各个版本都有的表格了。。。您们慢参考我就不重复劳动了。

好吧 SQL server 2008 中没有EOMONTH函数 那只能用dateadd拼接的方法来做

DECLARE
@date
DATETIME
=
'2000-03-02';

select
dateadd(dd,-day(@date),dateadd(m,1,@date))
AS
'Last Day Of This Month',

         dateadd(dd,-day(@date),dateadd(m,2,@date))
AS
'Last Day Of Next Month',

         dateadd(dd,-day(@date),dateadd(m,0,@date))
AS
'Last Day Of Previous Month',

         dateadd(dd,-day(@date),dateadd(m,-1,@date))
AS
'LAST Last Day Of Previous Monthh'
