Check This.

    declare @D varchar(20)
    set @D ='JAN-2017'
    select  
    datediff(day, '01-'+@D, dateadd(month, 1,'01-'+ @D)) as NoOfDay

try this.......... enter code here

SELECT day(GETDATE() )

Answer 3

在Sql Server中，您可以在指定月份的第一天进行操作

select datediff(day, @date, dateadd(month, 1, @date))

Answer 4

For MySQL users...

SET @convertedDate = STR_TO_DATE( CONCAT( '01-',
                                          'Jan-2017' ),
                                  '%d-%b-%y' );
SELECT DATEDIFF( DATE_ADD( @convertedDate,
                           INTERVAL 1 MONTH ),
                 @convertedDate ) AS NumOfDays;

“ Feb-2017”位是您的列或变量

SELECT DATEPART(DAY, EOMONTH('01-' + 'Feb-2017'))
