title: Which JOIN is correct to use when using FUNCTION?
body: <p>Take this sample code...</p>
  
  <pre><code>SELECT Persons.name,
         getCarModelID(Persons.ID) AS car_model -- &lt; A function 
  
  FROM   Persons
         LEFT OUTER JOIN Cars ON getCarModelID(Persons.ID) = Cars.ID
  </code></pre>
  
  <p>In the sample above, is it correct to use "LEFT OUTER JOIN"?</p>
