如何使用不同的數據庫模式使用 JPQL？

Question

在 SQL Server 數據庫中，我有一個映射到 JPA 的表：

@Table(name = "Demandas", catalog = "DIAGE", schema = "ade")

有三個表（ DemandaExecutivo 、 DemandaGerente 、 DemandaAssessor ）是連接表，它們是由 ORM 在不同架構（ dbo ，SQL Server 中的默認架構）下自動創建的，而項目中的所有其他表都映射到（架構ade ，如上面的代碼所示）：

@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;

我已經構建了一個 JPQL 來使用一個 ( ade ) 表查詢這 3 個 ( dbo ) 表：

@NamedQuery(name = "Demandas.findAllByMatricula", query = "SELECT d FROM Demandas d INNER JOIN DemandaExecutivo e ON d.id = e.idDemanda INNER JOIN DemandaGerente g ON d.id = g.idDemanda INNER JOIN DemandaAssessor a ON d.id = a.idDemanda WHERE (d.prefixo.prefixo = :prefixo) AND d.status.idStatus IN (1,2,3,4,5,7) AND d.situacao.idSituacao IN (1,2,3,4,5) AND (e.Matricula= :matricula OR g.Matricula = :matricula OR a.Matricula = :matricula)"),

但由於dbo架構未映射，因此無法編譯：

抽象模式類型 [表名] 未知

有誰知道我該如何修復它以便我可以使用上面的 JPQL ？

提前致謝。

Answer 1

我想你可能誤解了這個錯誤。 問題在於 JPQL 而不是正在使用的 SQL。 JPQL 需要實體，並且您在查詢中定義的 DemandaExecutivo 或 e.Matricula 字段沒有任何實體。 您將訪問 uorPosCollection、uorPosCollection1 和 uorPosCollection1 集合，JPA 將根據您的映射執行必要的連接

查詢應該更接近於：“SELECT d FROM Demandas d join d.uorPosCollection e d.uorPosCollection1 g d.uorPosCollection2 a WHERE (d.prefixo.prefixo = :prefixo) AND d.status.idStatus IN (1,2,3 ,4,5,7) AND d.situacao.idSituacao IN (1,2,3,4,5) AND (e.matricula= :matricula OR g.matricula = :matricula OR a.matricula = :matricula)"

這假設 UorPos 實體具有您傳遞給查詢的類型的矩陣字段。

如果不是這種情況，您將需要使用本機 SQL 查詢並自己傳入表和架構。
