您可以创建一个这样的函数来生成Month和do SELECT dbo.fn_GetMonthFromDate(date_column)作为月份FROM table_name /******对象:UserDefinedFunction [dbo]。[fn_GetMonthFromDate]脚本日期:11/16/2018 10:26:33 AM ******/ 设置ansi_nulls为on 去 设置quoted_identifier为on 去 CREATE FUNCTION [dbo].[fn_GetMonthFromDate] (@date datetime) 返回varchar (50) 作为 开始 声明@monthPart int

SET @monthPart = MONTH(@date) IF @monthPart = 1 BEGIN RETURN 'January' END ELSE IF @monthPart = 2 BEGIN RETURN 'February' END ELSE IF @monthPart = 3 BEGIN RETURN 'March' END ELSE IF @monthPart = 4 BEGIN RETURN 'April' END ELSE IF @monthPart = 5 BEGIN RETURN 'May' END ELSE IF @monthPart = 6 BEGIN RETURN 'June' END ELSE IF @monthPart = 7 BEGIN RETURN 'July' END ELSE IF @monthPart = 8 BEGIN RETURN 'August' END ELSE IF @monthPart = 9 BEGIN RETURN 'September' END ELSE IF @monthPart = 10 BEGIN RETURN 'October' END ELSE IF @monthPart = 11 BEGIN RETURN 'November' END ELSE IF @monthPart = 12 BEGIN RETURN 'December' END RETURN NULL END

SUBSTRING('JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC ', (@intMonth * 4) - 3, 3)

有点俗气，但应该有用:

SELECT DATENAME(month, DATEADD(month, @mydate-1, CAST('2008-01-01' AS datetime)))

在希伯来语等一些语言环境中，闰月取决于年份，因此为了避免在这些语言环境中出现错误，您可以考虑以下解决方案:

SELECT DATENAME(month, STR(YEAR(GETDATE()), 4) + REPLACE(STR(@month, 2), ' ', '0') + '01')     

SQL server中没有系统定义的函数。但是您可以创建自己的用户定义函数—标量函数。您可以在数据库的对象资源管理器中找到标量函数:可编程性->函数->标量值函数。下面，我使用一个表变量将它们结合在一起。

--Create the user-defined function
CREATE FUNCTION getmonth (@num int)
RETURNS varchar(9) --since 'September' is the longest string, length 9
AS
BEGIN

DECLARE @intMonth Table (num int PRIMARY KEY IDENTITY(1,1), month varchar(9))

INSERT INTO @intMonth VALUES ('January'), ('February'), ('March'), ('April'), ('May')
                           , ('June'), ('July'), ('August') ,('September'), ('October')
                           , ('November'), ('December')

RETURN (SELECT I.month
        FROM @intMonth I
        WHERE I.num = @num)
END
GO

--Use the function for various months
SELECT dbo.getmonth(4) AS [Month]
SELECT dbo.getmonth(5) AS [Month]
SELECT dbo.getmonth(6) AS [Month]

您可以创建一个这样的函数来生成Month和do SELECT dbo.fn_GetMonthFromDate(date_column)作为月份FROM table_name /******对象:UserDefinedFunction [dbo]。[fn_GetMonthFromDate]脚本日期:11/16/2018 10:26:33 AM ******/ 设置ansi_nulls为on 去 设置quoted_identifier为on 去 CREATE FUNCTION [dbo].[fn_GetMonthFromDate] (@date datetime) 返回varchar (50) 作为 开始 声明@monthPart int
