项目中用到别人创建的数据库，不能修改数据库结构，商品表中有个销售价格字段 sell_price decimal(11,2)，要对它进行比较查询，大致就是要查价格处于什么范围的商品，这里以大于或等于为例(即最低价格)。Condition类未查询条件类，里面有id和minPrice等属性。我用hibernate3操作数据库，报出如下错误，请知道解决办法的仁兄不灵赐教，不胜感激。
实现代码
[code="java"]
public List getProductsList(Condition condition){
String hql = "FROM Products p WHERE 1=1 AND p.pid=:id AND p.sell_price >= :min"
Query query = getSession().createQuery(hql);
query.setLong("id", condition.getId());
query.setBigDecimal("min", condition.getMinPrice());
//query.setDouble("min", condition.getMinPrice().floatValue());
}
Condition c = new Condition();
c.setId(2);
BigDecimal min= new BigDecimal("20.00");
c.setMinPrice(min);
[/code]
