Question

I have three tables, a User table, a Company table, and a linking table that assigns user roles. I am trying to update the user_role table so that all users of their associated companies have the same role. The role table looks something like this:

+---------+---------+------------+
| role_id | user_id | company_id |
+---------+---------+------------+
|       2 |      54 |         30 | 
|      15 |       1 |         15 | 
|      14 |      87 |         32 | 
|      15 |      88 |         33 | 
|      15 |     106 |          3 | 
+---------+---------+------------+

What I want to logically do is something like this

INSERT INTO user_role 
    (user_id, company_id, role_id) 
VALUES (
         (SELECT user_id FROM user_role WHERE company_id = ##FIRST COMPANY_ID IN LIST##), 
         (##LIST OF COMPANY_ID'S##), 2
       );

I have a static list of company_id’s, and I want all users that have any role in that company to be assigned an additional static role_id in this table. What is the best way to accomplish this? Should I look at a stored procedure?

Answer 1

INSERT INTO user_role (user_id, company_id, role_id) 
SELECT user_id, company_id, { new role id here }
  FROM user_role 
 WHERE company_id in ( { list of company id's here })
