Question

我有一个我正在尝试执行的HQL查询，但是我一直收到QueryException。

我的查询是

SELECT a FROM (SELECT MAX(m.version) maxVersionOp, m.codoperacion codOp FROM ConsumoMe m WHERE m.codoperacion  IN ('MEL101','MEL102') AND m.horizontetemporal IN('PM') GROUP BY m.codoperacion), ConsumoMe a WHERE codOp = a.codoperacion AND maxVersionOp = a.version AND a.fechaBajaLogica IS NULL

我得到的例外：

org.hibernate.QueryException: in expected: SELECT [SELECT a FROM (SELECT MAX(m.version) maxVersionOp, m.codoperacion codOp FROM es.enagas.siomprog.entities.ConsumoMe m WHERE m.codoperacion  IN ('MEL101','MEL102') AND m.horizontetemporal IN('PM') GROUP BY m.codoperacion), es.enagas.siomprog.entities.ConsumoMe a WHERE codOp = a.codoperacion AND maxVersionOp = a.version AND a.fechaBajaLogica IS NULL]

如果我剪切内部选择并尝试执行它：

SELECT MAX(m.version) maxVersionOp, m.codoperacion codOp FROM ConsumoMe m WHERE m.horizontetemporal IN('PM') AND (m.codoperacion = 'MEL101' OR m.codoperacion = 'MEL102') GROUP BY m.codoperacion

然后我得到了一个类似的例外：

org.hibernate.QueryException: , expected in SELECT [SELECT MAX(m.version) maxVersionOp, m.codoperacion codOp FROM es.enagas.siomprog.entities.ConsumoMe m WHERE m.horizontetemporal IN('PM') AND (m.codoperacion = 'MEL101' OR m.codoperacion = 'MEL102') GROUP BY m.codoperacion]

如果我运行SQL等效查询，我会得到有效的结果。此外，那些错误消息“，在SELECT中预期”并不是很有帮助。知道可能出现什么问题吗？

Answer 1

我在SQL中看到了多个错误

m.codoperacion codOp - ＆gt; m.codoperacion as codOp

AND m.horizontetemporal IN('PM') AND GROUP BY m.codoperacion - ＆gt;不应该有AND

AND m.horizontetemporal IN('PM') GROUP BY m.codoperacion

Answer 2

答案在：

http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/queryhql.html#queryhql-subqueries

Hibernate不允许from子句中的子查询。

转换查询时出现hibernate.QueryException
