title: Using LIKE with parameter expression in query
body: <p>I was trying to using the like function in <em>iReport 4.0.1</em>. Checked online but none seem to work. <br/> 
  Currently trying to use:</p>
  
  <pre><code>where  name  LIKE'%$P!{px_name}%'
  </code></pre>
  
  <p>also tried </p>
  
  <pre><code>'%$P{px_name}%'
  </code></pre>
  
  <p>but when running the report it comes up saying 'No document'. </p>
  
  <p>But when using  <code>where name =$P{px_name}</code> it works perfectly fine.</p>
