我尝试使用hibernate实现这一点(MySQL),以创建一个包含给定日期每笔交易的票据数量的报告。我认为这是非常清楚和自我描述的:
select customer.trade, COUNT(*) from customer join note where customer.customer_id=note.customer_id and note.CREATION_TS like '${DATE}%' group by customer.trade;
到目前为止,我有这个。“%”是通配符:
Query query = session.createQuery(
"select new ReportEntry(c.trade, count(*)) from customer as c join note as n where c.id=n.customer.id and n.creationDate like ':creationDate%' group by c.trade;")
.setParameter("creationDate", DATE_FORMAT.format(reportDate));
不幸的是,我得到:
unexpected token: ':creationDate%'
用{}封装不起作用。打开和关闭属性id的正确方法是什么?
