title: MYSQL auto fill column values from another table
body: <p>im very new to databases :) now with that said.</p>
  
  <p>I have a table <strong>(sellers)</strong> with the columns: <em>Seller_id, Seller_logo</em>. There are 5 sellers.
  I have a table <strong>(details)</strong> with the columns : <em>Details_id, Seller_logo, Product, Price</em>. There are 1000 Products.</p>
  
  <p>Today i decided to insert a new column at the <strong>(sellers)</strong> table, with name <em>"seller_name"</em> and i fill in the values very easy since there are just 5 sellers.</p>
  
  <p><strong>The problem :</strong> How can i add in the <strong>(Details)</strong> table, a new column <em>"seller_name"</em> and automatic fill the values of the from the <strong>(sellers)</strong> table?
  <br><br>*i created a relation between <em>Seller_logo</em> on the tables <strong>(Sellers and Details)</strong></p>
  
  <p>Thanks in advance.</p>
