Question

I have two tables, one called product_text with a products name, description and category. The other called product_price with the products selling_price and cost_price.

I want to update the product_price table with generic values, for example, the cost_price as 0.01 and the selling_price as 0.01

I need to somehow insert this information into the product_price table for each row that exists in the product_text table.

For example, if I have:

id name     description category
1  example  example     hats
2  example2 example2    socks

in the product_text table, I want to insert:

id selling_price cost_price
1  0.01          0.01
2  0.01          0.01

into the product_price table.

I want to do this for a million items, so need an efficient way of doing it.

Please help

Answer 1

insert into product_price (id, selling_price, cost_price)
select id, 0.01, 0.01 from product_text
