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

I believe you are looking for:

insert into  productHistory 
       ( id_h
       , id_product 
       , name
       ) 
  select next value for product_history_seq
       , id_product 
       , name 
    from product 
;

Answer 2

INSERT INTO productHistory (id_h, id_product, name)
  (SELECT
    product_history_seq.nextval,
    id_product,
    name
  FROM product);

That works

Answer 3

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

Answer 4

"insert into yourtableone select default, val1, val2 from yourtabletwo" and declare the id as genereated by default
