爱码少年 启动的时候JPQL有一个解析成SQL对应关系的过程,原生SQL没这个过程,去掉报错是因为你的JPQL错误。

错误提示说:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.model.goods.Goods g.goodsId, g.goodsName, g.goodsIcon, gs.goodsPrice from Goods' at line 1,是你的sql语句写错了。

Springboot启动时报错:Caused by: java.sql.SQLSyntaxErrorException: ORA-02275: 此表中已经存在这样的引用约束条件。关于JPA的使用
使用的是Oracle数据库, 在数据库中我已经创建好了表,表之间的主外键关系我是手动来创建的。 userrolerecid references md_role(recid) not null, userclassrecid references md_class(recid) not null , 类似这样的关系。 然后在使用jpa的时候 我是这样创建bean的 @OneToOne(cascade=CascadeType.ALL) //级联操作 @JoinColumn(name="userrolerecid",referencedColumnName="recid") private RoleInfo roleInfo; @OneToOne(cascade=CascadeType.ALL) //级联操作 @JoinColumn(name="userclassrecid",referencedColumnName="recid") private ClassInfo classInfo; 然后就报类似于这样的错误 Caused by: java.sql.SQLSyntaxErrorException: ORA-02275: 此表中已经存在这样的引用约束条件 请问怎么解决?

JAVA 使用jpa原生sql查询字段 别名无值,小白求大神慷慨赐教
sql查询语句 ,其中 realPrice 是别名 ``` @Query(value = "select *,case when db.order_type_code = 'Db2bOrder' then d.RealTotal else df.TotalMoney end realPrice from db2border_bill_detail db " + "left join db2border d on d.fID =db.source_id " + "left join db2brefund df on df.OrderID = db.source_id where db.group_id = ?1 and db.db2border_bill_id = ?2", nativeQuery = true) List<Db2BorderBillDetail> findAllByGroupIdAndDb2BorderBillId(String groupId,Long Id); ``` 在Db2BorderBillDetail实体类增加对应字段,这样查询正常 ,返回的realPrice的字段有值 ,但是发现保存报错 提示“Unknown column 'db2borderb0_.realPrice' in 'field list'” ``` @Transient() private BigDecimal realPrice; public BigDecimal getRealPrice() { return realPrice; } public void setRealPrice(BigDecimal realPrice) { this.realPrice = realPrice; } ``` 改成这样 则保存正常,但是sql查询的值就为null ``` private BigDecimal realPrice; @Transient() public BigDecimal getRealPrice() { return realPrice; } public void setRealPrice(BigDecimal realPrice) { this.realPrice = realPrice; } ``` 求大神赐教下,怎么才能查询保存都正常

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
