Question

我有如下查询。但是当它被执行时，我收到错误消息意外令牌：

select d from DimensionStone d inner join d.stockRegister s 
where d.stockRegister.stockRegisterId <=? and s.application.applicationId=? 
and d.isIssued='No' or (s.stockRegisterId <=? and d.isIssued='Yes' 
and d.issuedDate>(select max(updatedOn) from StockRegister st 
where st.stockRegisterId<? and st.application.applicationId=?)) 
except (select d1 from DimensionStone d1 inner join d1.stockRegister s1 
where s1.stockRegisterId <=? and s1.application.applicationId=? and 
d1.isIssued='No')

我如何才能解决这个问题。我已经通过google搜索了足够的内容。但是我找不到想要的答案。请帮帮我

Answer 1

except不是有效的HQL关键字;如果要使用特定的RDBMS语法 Session.createSQLQuery(String sql)和ResultTransformer将每个记录集行映射到对象DimensionStone

Answer 2

替换除非存在：

select d from DimensionStone d inner join d.stockRegister s 
where d.stockRegister.stockRegisterId <=? and s.application.applicationId=? 
and d.isIssued='No' or (s.stockRegisterId <=? and d.isIssued='Yes' 
and d.issuedDate>
    (select max(updatedOn) from StockRegister st 
    where st.stockRegisterId<? and st.application.applicationId=?)) 
and not exists
    (select 'next' from DimensionStone d1 inner join d1.stockRegister s1 
    where s1.stockRegisterId <=? and s1.application.applicationId=? and 
    d1.isIssued='No')

Answer 3

关键字EXCEPT似乎不是由HQL处理的（既不是MINUS），我也得到了与你相同的例外。
我实现了使用关键字重现except查询的行为：NOT IN（NOT EXISTS也可以工作）
例如：

SELECT a FROM MyTable a WHERE a NOT IN (SELECT a FROM MyTable a, otherTable l WHERE l.id = ?1 AND l.myObject.id = a.id)

除了hibernate中的子句
