title: My Batis delete query return type not consistent
body: <p>I am using spring-mybatis for a Delete query</p>
  
  <p>this is how my calls look like</p>
  
  <pre><code>if(mapper.deleteSomething(id))
  {
  
  .....
  }
  </code></pre>
  
  <p>And in my mapper i have</p>
  
  <pre><code>&lt;delete id = "deleteSomething"&gt;
  delete from table where id = #{id}
  &lt;/delete&gt;
  </code></pre>
  
  <p>However I noticed that return type is not always true in case of successful deletion. Sometimes it returns true and sometimes false, But the records are always deleted in db.</p>
  
  <p>What am I doing wrong?</p>
