title: org.springframework.data.jpa.repository.Query Params wrong result
body: <p>Hi I have a problem with result of this method:</p>
  <pre><code>@Query(value = &quot;select * from Mail where sent_Flag = 0 and scheduled &lt; '?1'&quot;, nativeQuery = true)
      public List&lt;Mail&gt; getToSend(Long timestamp);
  </code></pre>
  <p>If I put value 0 or current timestamp result is the same (returns all records like scheduled 1=1), If I try to run it via SQL directly everything works, where is a problem?</p>
  <p>I'm using SQLite and springboot</p>
