title: SQL join or concatenate multiple record text fields with same foreign key
body: <p>This is probably a simple question that for some reason I just cannot see the answer. Here is sample data:</p>
  
  <pre><code>+----+----------+---------------------------+
  | ID | F_Key_ID |        Desc_Text          |
  +----+----------+---------------------------+
  |  1 |      15  | This is an example        |
  |  2 |      15  | that I wished worked      |
  |  3 |      15  | correctly                 |
  |  4 |      21  | Unique entry              |
  |  5 |      18  | The Eagles are            |
  |  6 |      18  | the best football team.   |
  +----+----------+---------------------------+
  </code></pre>
  
  <p>Please excuse the noob table. How awful is that?!</p>
  
  <p>What I'd like is some SQL that takes the text common to each F_Key_ID and concatenates it together like this:</p>
  
  <pre><code>+----------+---------------------------------------------------+
  | F_Key_ID |                    Concat_Text                    |
  +----------+---------------------------------------------------+
  |       15 | This is an example that I wished worked correctly |
  |       21 | Unique entry                                      |
  |       18 | The Eagles are the best football team.            |
  +----------+---------------------------------------------------+
  </code></pre>
  
  <p>Thanks in advance!</p>
