How do I use an INSERT INTO with this PL/SQL code block?

Question

I'm fairly new to the procedural language side of PL/SQL, so forgive me if this is basic.

I'm trying to put values in a table I've previously created outside of this code block. This code is currently getting an error on the sixth line. Any idea why?

BEGIN
  FOR c IN (SELECT name FROM clients) LOOP
    FOR d IN (SELECT customer_id, alt_name FROM customers) LOOP 
      IF d.alt_name LIKE '%' || c.name || '%'
      THEN
            INSERT INTO previously_made_table(name, customer_id, alt_name, customer_code) VALUES(c.name, d.customer_id, d.alt_name, '101');
            COMMIT;
       END IF;
    END LOOP;
END LOOP;
END;

Answer 1

You don't need pl\sql here

insert into previously_made_table
  (name, customer_id, alt_name, customer_code) 
 select c.name, d.customer_id, d.alt_name, '101'
 from   clients c , customers d
 where  d.alt_name LIKE '%' || c.name || '%'

Answer 2

This worked.

INSERT INTO previously_made_table VALUES(c.name, d.customer_id, d.alt_name, '101');

I cut the column names. Hope that helps.
