You can modify a table using the result obtained from executing an inner join query on two additional tables by using the UPDATE statement with a JOIN clause. The following steps can be used to achieve this:

  1. Write an inner join query to join the two tables together based on a common column.
  2. Use the result obtained from the inner join query to update the target table using the UPDATE statement.
  3. Specify the JOIN clause in the UPDATE statement to update the target table with the result obtained from the inner join query.

For example, suppose you have two tables, "orders" and "customers", which are related by a common column "customerid". You can modify the "orders" table by updating the "customername" column with the corresponding customer names from the "customers" table using the following SQL statement:

UPDATE orders
JOIN customers ON orders.customer_id = customers.customer_id
SET orders.customer_name = customers.customer_name;

This statement will update the "orders" table by joining it with the "customers" table based on the "customerid" column, and updating the "customername" column in the "orders" table with the corresponding customer names from the "customers" table.
