title: SQL command doesn't return rows
body: <p>I have a SQL command which I know data exists with the criteria, but when I run the query it doesn't return rows:</p>
  
  <p><strong>SQL:</strong></p>
  
  <pre><code>SELECT `USER_ID`, `CAR_ID`, `AD_ID`, `BRAND`, `MODEL`
  , `YEAR`, `PRICE`, `MILEAGE`, `GEARBOX`, `STATUS`, `COLOR_IN`, `COLOR_OUT`
  , `BODY`, `FUEL`, `ABOUT`, `MAIN_PHOTO` 
  FROM (`ads`, `cars`, `ad_extras`) 
  WHERE `ads`.`USER_ID` = '2'
  </code></pre>
  
  <p>What should I do?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>When I do <code>SELECT *</code> it also doesn't return data.</p>
  
  <p>when I select from 2 tables it retaurns data. So I can't select from 3 tables right?</p>
