title: SELECT one column where condition is met
body: <p>I have table like this : </p>
  
  <pre><code>ID  Name_1            Name_2               Name_3
  1   Egon Spengler     Ives Dertway         Blade Ketlump
  2   Mac Taylor        Jedidiah Buckbolt    Sarah Connor
  3   Sarah Connor      Modesto Slowfell     Jean-Luc Picard
  4   Jean-Luc Picard   Beulah Cuxpan        Henry Jones
  5   Ellen Ripley      Adeline Finkdell     Ives Dertway
  6   James T. Kirk     Bertram Cam          Mac Taylor 
  7   Henry Jones       Vidal Matton         Bertram Cam
  </code></pre>
  
  <p>There is never same name in all three of the columns, so this cannot happen :</p>
  
  <pre><code>3   Sarah Connor      Sarah Connor     Sarah Connor
  </code></pre>
  
  <p>I would like to Select just one name which meets the condition LIKE = '%value%',
  Problem is I never know which row to select exactly and I don't want to select them all.
  People in this table are authors. There are also column about title of book, genre and so on.
  I want to do search only in authors of the books.</p>
  
  <p>Thank you for your help...</p>
