Passing a list into MySQL stored procedure and check ALL values are present

Question

I have a query, where I check the user has ALL the permissions present in a list of perms.

So, it\'s something like this...

SELECT DISTINCT account_id

This is what I've got so far...

Not ideal, but you can work out the length of the items in the string with this..

(SELECT LENGTH(permissions) - LENGTH( REPLACE(permissions, ',', '') ) + 1)

It basically counts all the commas in the string and uses that as the total number of perms passed in.

CREATE PROCEDURE has_permission( IN account_id BIGINT, IN permissions TEXT)
BEGIN
  SELECT DISTINCT account_id
  FROM   pp_acl_user_roles ur, pp_acl_role_permissions rp
  JOIN pp_acl_permissions p ON rp.permission_id=p.id
  WHERE (
    ur.account_id = account_id
    #check for permission ids OR keys depending on what has been passed in.
    AND ( FIND_IN_SET(p.id, permissions) OR FIND_IN_SET(p.key, permissions) )
    AND ur.role_id = rp.role_id

  )
  #ensure we have ALL the permissions we asked for, not just some -makes IN() an AND not an OR.
  GROUP BY ur.account_id
  HAVING COUNT(DISTINCT rp.permission_id) = (SELECT LENGTH(permissions) - LENGTH( REPLACE(permissions, ',', '') ) + 1);
