Liferay自定义SQL查询日期

Question

我正在尝试在liferay门户中编写自定义sql查询。以下是查询。

SELECT sum(score) as total FROM ratingsentry r  WHERE r.modifiedDate>?;

util函数如下。

String sql = CustomSQLUtil.get("GET_TODAY_COUNT");              
SQLQuery q = dbSession.createSQLQuery(sql);
QueryPos qPos = QueryPos.getInstance(q);        

Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
cal.add(Calendar.DATE, -1);               
java.sql.Timestamp timestamp = CalendarUtil.getTimestamp(cal.getTime());      
qPos.add(timestamp);

q.addScalar("total", Type.LONG );                                   
Object count=q.uniqueResult();

从上面的util方法中，te count总是返回为0。

非常感谢任何帮助。

请改为尝试：

Timestamp timestamp = new Timestamp(cal.getTimeInMillis());
