Java 如何使用不同的数据库模式使用JPQL？
在SQL Server数据库中，我有一个映射到JPA的表：Java 如何使用不同的数据库模式使用JPQL？,java,jpa,eclipselink,jpql,junction-table,Java,Jpa,Eclipselink,Jpql,Junction Table,在SQL Server数据库中，我有一个映射到JPA的表： @Table(name = "Demandas", catalog = "DIAGE", schema = "ade") 有三个表DemandExecutivo、DemandaGerente、DemandAssessor，它们是由ORM在不同的模式dbo下自动创建的，dbo是SQL Server中的默认模式，与项目中所有其他表映射到模式ade的模式不同，如上面的代码所示： @JoinTable(name = "DemandaExecu
@Table(name = "Demandas", catalog = "DIAGE", schema = "ade")
@JoinTable(name = "DemandaExecutivo", schema="dbo", joinColumns = {
@JoinColumn(name = "idDemanda", referencedColumnName = "id")}, inverseJoinColumns = {
@JoinColumn(name = "Matricula", referencedColumnName = "Matricula")})
@ManyToMany
private Collection<UorPos> uorPosCollection;
@JoinTable(name = "DemandaGerente", schema="dbo", joinColumns = {
@JoinColumn(name = "idDemanda", referencedColumnName = "id")}, inverseJoinColumns = {
@JoinColumn(name = "Matricula", referencedColumnName = "Matricula")})
@ManyToMany
private Collection<UorPos> uorPosCollection1;
@JoinTable(name = "DemandaAssessor", schema="dbo", joinColumns = {
@JoinColumn(name = "idDemanda", referencedColumnName = "id")}, inverseJoinColumns = {
@JoinColumn(name = "Matricula", referencedColumnName = "Matricula")})
@ManyToMany
private Collection<UorPos> uorPosCollection2;

我想你可能误解了这个错误。问题在于使用的是JPQL而不是SQL。JPQL需要实体，而您在查询中定义的DemandExecutivo或e.Matricula字段没有实体。您将访问UorpsCollection、UorpsCollection1和UorpsCollection1集合，JPA将根据您的映射执行必要的联接 查询应更接近： 从Demandas中选择d，加入d.UorpsCollection e d.UorpsCollection 1 g d.UorpsCollection 2 a，其中d.prefixo.prefixo=：prefixo和d.status.idStatus在1,2,3,4,5,7中，d.situacao.idSituacao在1,2,3,4,5中，e.matricula=：matricula或g.matricula=：matricula或a.matricula=：matricula=：matricula 这假设UorPos实体有一个矩阵字段，该字段的类型与您传递给查询的类型相同
如果不是这种情况，则需要使用本机SQL查询，并亲自传入表和架构。如果联接表位于不同的架构中，则必须在@JoinTable注释中定义，除非连接所隐含的默认值位于正确的位置。JPQL只是使用实体映射来生成SQL，但是如果您不提及某些表的位置，那么它将很困难。发布JPA生成的SQLprovider@BillyFrost，我已经用异常更新了这个问题，并且还通知了@JoinTablename=DemandaExecutivo，schema=dbo，joinColumns中的模式，但是异常仍然存在。由于项目不编译，有没有其他方法来获取JPA提供程序生成的SQL？我不使用该提供程序，因此无法对其错误的细节发表评论。它只是在查找实体DemandExecutivo、DemandaGerente和DemandAssessor时遇到问题吗？因为您的JPQL引用了它们，所以它们必须是实体。正如我在问题中提到的那样，JPQL并没有提到连接表，问题确实也是您所指的，我不知道如何解决它。由于这些连接表是自动生成的，如果我手动创建实体类并映射它们，是否会出现问题？这些名称是否连接表或实体？？？？如果它们不是实体，就不能在JPQL中使用。你说得对！非常感谢您向我澄清这一点。对于那些想知道的人，我以这种方式构建了JPQL:@NamedQueryname=Demandas.findAllByMatricula，query=选择不同于Demandas d的d.d内部联接d.uorpscollection e ON d.id=e.Demandas集合.id内部联接d.uorpscollection 1 g ON d.id=g.Demandas集合1.id内部联接d.uorpscollection 2 a ON d.id=a.Demandas集合2.id，其中d.prefixo.prefixo=：prefixo和e.matricula=：matricula或g.matricula=：matricula或a、 矩阵=：矩阵，。
