[SQL]複製一筆資料並自行指定主鍵值

最近剛好有用到... ↓

若[Index]具識別屬性：


                SET IDENTITY_INSERT [dbo].[Table] OFF
                GO
                INSERT INTO [Table] 
                (
                    [index]
                    ,[A]
                    ,[B]
                )
                SELECT 
                    3 AS [index]
                    ,[A]
                    ,[B]
                  FROM [Table]
                  WHERE [index] = 2
                GO  
                SET IDENTITY_INSERT [dbo].[Table] ON
                GO

若[Index]不具識別屬性：


                INSERT INTO [Table] 
                (
	                [index]
                    ,[A]
                    ,[B]
                )
                SELECT 
                    3 AS [index]
                    ,[A]
                    ,[B]
                  FROM [Table]
                  WHERE [index] = 2
