You can create a function like this to generate the Month and do SELECT dbo.fn_GetMonthFromDate(date_column) as Month FROM table_name

/****** Object:  UserDefinedFunction [dbo].[fn_GetMonthFromDate]    Script Date: 11/16/2018 10:26:33 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[fn_GetMonthFromDate] 
(@date datetime)
RETURNS varchar(50)
AS
BEGIN
    DECLARE @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
