How to populate a junction table from two tables with a query

I'm wondering if it is possible to populate a junction table with a SQL query from two already populate tables. For Example;

Products

id | name | price
--------------------------
1  |   Foo    |   0
2  |   Bar    |   0
3  |   Tmp  |   0

Packages

id | name
------------------------
1  | Bundle

The above two tables are already populated. Is there a SQL query that would enable me to populate the table below as shown.

Package Products

id | package_id | product_id
-------------------------------------------
1     1                     1
2     1                     2
3     1                     3

Thanks in advance.

Is there any relation between the existing two tables, it doesn't appear so?

No, unfortunately not. I'm currently migrating the data into a new schema so the relation between these two tables would be the table package_products which is of course the problem I am currently facing. There is also no relation between them from the old schema I am migrating from.

Well, to product the results you showed, you can do:

SELECT Packages.ID, Products.ID FROM Products, Packages;

Open in new window
