Java 执行HQL查询时发生org.hibernate.queryexception错误

我正在HQL中执行查询，得到以下错误。我使用DB2作为数据库

Error: Caused by:  org.hibernate.queryexception: in expected  [hql query]

问题是

final String qStr = "select distinct a.* from (select attr.* from AttributeModel attr, BOModel bo, BusinessIdentifierModel ident, NameTransferModel name, NameTransferModel name2 WHERE" +
                                    "bo.businessIdentifierId = ident.businessIdentifierId AND" +
                                    "ident.businessIdentifier = :businessIdentifier AND" +
                                    "attr.compAttributeModelKey.boRowNo = bo.compBOModelKey.boRowNo AND" +
                                    "attr.compAttributeModelKey.eventId = bo.compBOModelKey.eventId AND" +
                                    "bo.typeId = name.nameTransferId AND" +
                                    "name.originalName = :className AND" +
                                    "bo.nameId = name2.nameTransferId AND" +
                                    "name2.originalName = :fieldName) a JOIN (SELECT event.eventId, attr2.nameTransferId, attr2.compAttributeModelKey.boRowNo, RANK() OVER (PARTITION BY bo2.businessIdentifierId, attr2.nameTransferId, attr2.compAttributeModelKey.boRowNo ORDER BY event.eventId desc ) rank from EventModel event, BOModel bo2, AttributeModel attr2,BusinessIdentifierModel ident  WHERE" +
                                                                        "event.changeTime <= :time AND" +
                                                                        "bo2.businessIdentifierId = ident.businessIdentifierId AND"+
                                                                        "bo2.compBOModelKey.eventId = event.eventId AND" +
                                                                        "attr2.compAttributeModelKey.eventId = event.eventId AND" +
                                                                        "attr2.compAttributeModelKey.boRowNo = bo2.compBOModelKey.boRowNo AND" +
                                                                        "ident.businessIdentifier = :businessIdentifier) b ON (" +
                                                                        "a.eventId = b.eventId AND" +
                                                                        "a.nameTransferId = b.nameTransferId AND" +
                                                                        "a.boRowNo = b.boRowNo AND" +
                                                                        "RANK = '1')";

请看一眼，如果有任何语法错误，请告诉我第一个错误实际上在消息中

Error: Caused by:  org.hibernate.queryexception: **in** expected  [hql query]

预计将有一个新的进展

我真的不理解你的加入。

您在第二个子选择上的加入，应该是where IN吗？

…我猜这是在抱怨where和关键字后面没有空格？不管怎样，你不应该有更多来自异常的消息吗？还有更多的堆栈跟踪吗？感谢发条缪斯，我已经尝试给空间。但我还是得到了同样的例外。请告诉我是否有任何错误的语法？然后请更新这里的示例以反映这一点。快速浏览并不会发现任何明显的错误，但我希望从引擎中得到堆栈跟踪的其他部分的更好解释。它必须有更多的信息。
