MySql query double WHERE clause

Question

I currently have a query that checks whether a certain word is found in the array values.

$imploded = implode("','",$company_array); 
$query = "SELECT * 
          FROM $wpdb->usermeta 
          WHERE meta_key='company' 
          AND meta_value IN ('".$imploded."')";

The $company_array contains different values.

I want to add another WHERE clause but don't know how.
It should check on the users role:

SELECT*
FROM $wpdb->usermeta
WHERE meta_key = 'wp_capabilities'
AND meta_value = 'subscriber'

Maybe some sort of join queries? I have no clue.

==== Sample data and expected output ====
This is my current query

$query = "SELECT * 
          FROM $wpdb->usermeta 
          WHERE meta_key='company' 
          AND meta_value IN ('".$imploded."')";

I want to add the following query

SELECT*
FROM $wpdb->usermeta
WHERE meta_key = 'wp_capabilities'
AND meta_value = 'subscriber'

The first query loads a list of users that work for a certain company. The problem is................

Crap. I just realised something while writing this.
The problem was that the administrator is also listed in the list of users. I wanted him out of the results.
The users are listed based upon their value in the company field. But if that is empty the admin isn't listed anywhere.

Answer 1

Your WHERE clause needs to be

WHERE (meta_key='company' AND meta_value IN ('".$imploded."'))
   OR (meta_key = 'wp_capabilities' AND meta_value = 'subscriber')

Answer 2

try like this

$query = "SELECT * 
          FROM $wpdb->usermeta 
          WHERE (meta_key='company' 
          AND meta_value IN ('".$imploded."')) or (meta_key = 'wp_capabilities' and meta_value = 'subscriber')";

Answer 3

I think you required below. Note the () with OR for your both where clauses.

$query = "SELECT * 
          FROM $wpdb->usermeta 
          WHERE ( meta_key='company' AND meta_value IN ('".$imploded."')") 
          OR (meta_key = 'wp_capabilities' AND meta_value = 'subscriber');
