db2 query insert from another table

Question

I have a table product(id_product , name );

I have another one: productHistory (id_H , id_product , name);

I wanna create a query (db2) to insert all the row

Answer 1

Make id_h auto increment and try this

  insert into  productHistory ( id_product , name) values (select id_product , name from product );

id_h will auto-increment no need to put it in query

Hope it will help
