Hoping someone can point me in the right direction....

I have a table in Firebird of 'Parts' and a separate table of 'Warehouses'.
I need to populate a table of 'Stock_On_Hand' that is basically a join table
that resolves the many-to-many relationship of parts and warehouses.

I would like to create an After Insert trigger in both the Parts and
Warehouses table so that when a new Part or Warehouse is created, it will
create a corresponding record in the Stock_on_hand table for each
combination of Parts & Warehouses so that I can store stock on hand quantity
data.

That part is ok, and I'm fine with creating the triggers for this.

But I need to create a SQL Script that will take my current data in Parts &
Warehouses and create these records for each corresponding row in these
tables to initially populate this table.

Can someone steer me in the right direction as to what this SQL script
should look like? I believe I should be able to do this with an INSERT
statement but I'm pretty new to SQL and would appreciate any pointers in the
right direction.

Thanks
Myles
