字段中相同数据的区分开,求相同数据的第一条解决方法

CREATE TABLE [dbo].[Wound](    [WoundID] [int] IDENTITY(1,1) NOT NULL,    [Winding] [varchar](50) NULL,        [TF_ID] [int] NULL, CONSTRAINT [PK_Wound] PRIMARY KEY CLUSTERED (    [WoundID] ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]) ON [PRIMARY]GOinsert into Wound values('NP1',1)insert into Wound values('NP1',1)insert into Wound values('NP2',1)insert into Wound values('NP3',1)insert into Wound values('NP2',1)insert into Wound values('NP3',2)insert into Wound values('NP3',2)insert into Wound values('NP1',2)insert into Wound values('NP1',2)

select * from Wound T where not exists (select 1 from Wound where T.[Winding]=[Winding] and T.[TF_ID]=[TF_ID] And T.[WoundID]>[WoundID] )
