将具有标准值的另一个表的列中的所有记录插入到表中

Question

I have two tables, shops and products. Table shop with columns shopId (PK) and shopName. Another table Products has columns productId (PK) and productName. Because I have a relationship many-many between two tables I create another table shopProduct with two columns shopId and productId.

For example I have shop1 with id=1 and I have shop2 with id=2, product1 with id=1 and product2 with id=2. and the records of the table shopProduct is 1-1 ,2-2.

But now I want to have a product3 with id=3 that apply to all shops.

I consider in the real problem that i have about 250 shops.

How can implement this without a stored procedure?

I don't want to do of course 250

insert into shopProduct (shopId, productId) 
values (@shopId,@productId).

Can I do for loop for example to feed the the shopId value every time?The other value for product id is the same every time.

Answer 1

From my understanding of this question, try this... Seems too simple, but...

Insert into ShipProduct (ProductID, ShopID)
Select 3, ShopID
From Shops
