HQL多条件查询判断的问题

Question

有客户、编号、发货日期、截止日期4个查询条件，查询出对应的记录的条数，我的HQL查询代码如下：
[code="java"]
public Long getCount(String soNumber, Long customerID, Date startDate, Date endDate) {
String hql = "select count(*) from SalesOrder salesOrder where 1=1";
if(!"".equals(soNumber)){
hql =hql+" and sal.soNumber=?";
}
if(customerID!=null){
hql= hql+" and sal.customer.customerID =?";
}if(startDate!=null){
hql=hql+" and sal.jiaohuoriqi >=? and sal.jiaohuoriqi<=?";
}

Object[] count =new Object[]{soNumber,customerID,startDate,endDate};
return (Long)this.getHibernateTemplate().find(hql,count).get(0);
}
[/code]我的问题是 我把参数放在了数组里面，对应不同的情况数组怎么判断？

Answer 1

参数直接放进来就好了啊

public Long getCount(String soNumber, Long customerID, Date startDate, Date endDate) {
String hql = "select count(*) from SalesOrder salesOrder where 1=1";
if(!"".equals(soNumber)){
hql =hql+" and sal.soNumber="+soNumber;
}
if(customerID!=null){
hql= hql+" and sal.customer.customerID ="+customerID;
}if(startDate!=null){
hql=hql+" and sal.jiaohuoriqi >='"+startDate+"' and sal.jiaohuoriqi<= '"+endDate+"'";
}

      return (Long)this.getHibernateTemplate().find(hql).get(0);
}
