This is air code as I don't have anything to work with but I believe the basic logic is sound.  Let me know if you have any problems.

CREATE PROCEDURE CopyChildProducts
(
   @FomProductID INT,
   @ToProductID INT
)
AS

DECLARE @CurrProductID INT
   @NewProductID INT;

DECLARE crsProduct CURSOR FOR
SELECT ProductID
FROM Products
WHERE ParentProductID = @FromProductID;

OPEN crsProduct;
FETCH NEXT FROM crsProduct INTO @CurrProductID;

WHILE @@FETCH_STATUS = 0
BEGIN
   INSERT INTO Products (ParentProductID)
   VALUES (@ToProductID)

   SET @NewProductID = SCOPE_IDENTITY()

   EXECUTE CopyChildProducts @FromProductID = @CurrProductID,
      @ToProductID = @NewProductID

   FETCH NEXT FROM crsProduct INTO @CurrProductID;
END

CLOSE crsProduct
DEALLOCATE crsProduct

I modify the SP to be
ALTER PROCEDURE [dbo].[CopyChildProducts] 
	-- Add the parameters for the stored procedure here
	  @FromProductID INT,   @ToProductID INT
AS
BEGIN


DECLARE @CurrProductID INT,   @NewProductID INT;

DECLARE crsProduct CURSOR FOR
	SELECT ProductID
	FROM Products
	WHERE ParentProductID = @FromProductID;

OPEN crsProduct;
FETCH NEXT FROM crsProduct INTO @CurrProductID;

WHILE @@FETCH_STATUS = 0
BEGIN
   INSERT INTO Products (ParentProductID ,[ProductNameEN)   
   
      select @ToProductID, ProductNameEN]
           From Products where ProductID= @FromProductID 

   SET @NewProductID = SCOPE_IDENTITY()

   EXECUTE CopyChildProducts  @CurrProductID,  @NewProductID

   FETCH NEXT FROM crsProduct INTO @CurrProductID;
END

CLOSE crsProduct
DEALLOCATE crsProduct 
END

Open in new window

but I have some problems , it copy first level only and put them inside each other

I believe there is a syntax issue in the INSERT clause, should be...

      INSERT INTO Products (ParentProductID ,ProductNameEN)  
      SELECT @ToProductID, ProductNameEN
      FROM Products where ProductID= @CurrProductID

You can try this. You can assign whatever ParentProductID you want in the below code.
DECLARE @ParentProductID INT
SELECT @ParentProductID = 564
;WITH cte AS(
SELECT ProductID, ParentProductID,ParentProductID TopLevelParent
  FROM Test
 WHERE ParentProductID = @ParentProductID
 UNION ALL
SELECT c.ProductID, c.ParentProductID, p.TopLevelParent 
  FROM Test c
  JOIN cte p
    ON c.ParentProductID = p.ProductID
)
SELECT ProductID, TopLevelParent FROM cte

You want an SP? If the code posted works for you, It can be easily converted into an SP. Let me know.

alright. I am here to help and gain knowledge by helping. If my posts won't help you, you can obviously look for more experts comments.
 
The more information, detailed explanation you can provide, the faster you can get an answer.

When you said the code posted not works as required, you need to explain what is required and where the current script is lagging. If you cannot explain, its tough to answer and I can ignore your question right here.

Finally, I am here as a volunteer and don't get dollars for answering the questions. Time is important for everyone and I answer the questions in my leisure time only.
