Copy rows from the same table and update the ID column

Question

I have the following table

I have inserted Product B to it and it gives me an ID of 15

Answer 1

if you want to select all items (in condition the table not contains any primary keys)

INSERT INTO [tabelName]
SELECT  * FROM    [tabelName]
WHERE  (YourCondition)

in condition the table contains a primary keys, select only the columns that not primary key Like:

INSERT INTO [tabelName]
SELECT  col_1,col_2,col_n FROM    [tabelName]
WHERE  (YourCondition)
