MS SQL 当记录不存在时插入insert INTO not exists

INSERT INTO dbo.[T_DabaoTemp]  ([PType]
           ,[pID]
           ,[NewVersion]
           ,[ParentCode]
           ,[Addtime])
 select 0,5,'2.0.1','0_3',GETDATE() WHERE not exists (
 select 1 from [T_DabaoTemp] where [PType]=0 and [pID]=5 and [NewVersion]='2.0.1')
