title: JDBCTemplate.queryForList returns empty list
body: <p>Could you please help to figure out why following Java code returns empty list </p>
  
  <pre><code>return this.getJdbcTemplate().queryForList(
      "select cn from group g, group_relationship r, " +
      "group_member m where g.name='administratorGroup' and g.group_id=r.group_id " +
      "and r.member_id=m.member_id and m.cn like ?", 
      String.class, 
      new Object[] { cn + "%" });
  </code></pre>
  
  <p>I tested using sqlplus, replace ? with 'd%', The query returns a list of cn start with d.</p>
