　　　　CREATE TABLE [dbo].[chexin](
	[f_id] [int] IDENTITY(1,1) NOT NULL,
	[yuefen] [int] NOT NULL,
	[1] [int] NOT NULL,
	[2] [int] NOT NULL,
	[3] [int] NOT NULL,
	[4] [int] NOT NULL,
	[5] [int] NOT NULL,
	[6] [int] NOT NULL,
	[7] [int] NOT NULL,
	[8] [int] NOT NULL,
	[9] [int] NOT NULL,

	[11] [int] NOT NULL,
	[12] [int] NOT NULL,
	[name] [varchar](50) NOT NULL,
	[gender] [varchar](20) NOT NULL,
 CONSTRAINT [PK__chexin__2911CBED571DF1D5] PRIMARY KEY CLUSTERED 
(
	[f_id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

select * from chexin  　

列转行（8月份之后的所有数据列转行）

SELECT * from
(SELECT yuefen, 8 as yue, "8" as b FROM chexin
union all
SELECT yuefen, 9 as yue, "9" as b FROM chexin
union all
SELECT yuefen, 10 as yue, "10" as b FROM chexin
union all
SELECT yuefen, 11 as yue, "11" as b FROM chexin
union all
SELECT yuefen, 12 as yue, "12" as b FROM chexin 
) chexin 
    where yuefen>=201608

查询8月、之后所有月的合计数据（包括8月）

select ‘a‘ d,‘sda‘ c,yuefen,name,gender ,
(
SELECT SUM(b) from
(SELECT yuefen, 201608 as yue, "8" as b FROM chexin
union all
SELECT yuefen, 201609 as yue, "9" as b FROM chexin
union all
SELECT yuefen, 201610 as yue, "10" as b FROM chexin
union all
SELECT yuefen, 201611 as yue, "11" as b FROM chexin
union all
SELECT yuefen, 201612 as yue, "12" as b FROM chexin 
) chexin 
    where yue>=201608 and yuefen>=201608) 合计
    from chexin  where yuefen >=201608

8月之后每个月的合计

SELECT yue,SUM(b) 合计 from
(SELECT yuefen, 201608 as yue, "8" as b FROM chexin
union all
SELECT yuefen, 201609 as yue, "9" as b FROM chexin
union all
SELECT yuefen, 201610 as yue, "10" as b FROM chexin
union all
SELECT yuefen, 201611 as yue, "11" as b FROM chexin
union all
SELECT yuefen, 201612 as yue, "12" as b FROM chexin 
) chexin where yue>=201608 group by yue
