Question

我有这个名为：

"SELECT new net.yy.domain.RemoteObject(r.id, r.name) 
FROM RemoteObject r LEFT JOIN r.tenant t
WHERE ((upper(r.name) like upper(:name) AND :name IS NOT NULL) OR :name IS NULL) 
AND ((upper(t.name) = upper(:tenant) AND :tenant IS NOT NULL) OR :tenant IS NULL)"

我在输入中使用姓名或租户来称呼它。使用Oracle和mySQL，一切都还可以。但是对于postgreSQL，部分＆＃34;或者XX是空的＆＃34;似乎被忽略了。我有错误消息：

Caused by: org.postgresql.util.PSQLException: ERROR: function upper(bytea) does not exist

请问您有什么想法吗？ HQL请求必须能够与Oracle，Mysql和PostgreSQL一起使用。

java类：

@Id
@Column(name = "ID")
@GeneratedValue(generator = "seq_ro_gen", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "seq_ro_gen", sequenceName = "SEQ_RO", allocationSize = 1, initialValue = 1)
private Long id;

@Basic
@Column(name = "NAME", length = 64, unique = true)
private String name;

@Basic
@Column(name = "LOWERNAME", length = 64, unique = true)
private String lowerName;

@Basic
@Column(name = "PK", columnDefinition = "BLOB")
private byte[] pk;

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "TENANTID", referencedColumnName = "ID")
private Tenant tenant;

... Some other fields ...

我用特定的postgresql文件覆盖（只有一些字段）：

<entity class="RemoteObject">
    <attributes>
        <id name="id">
            <generated-value strategy="IDENTITY"/>
        </id>
        <basic name="pk">
            <column name="PK" column-definition="text" />
        </basic>
        <basic name="name">
            <column name="NAME" column-definition="varchar" length="64" unique ="true" />
        </basic>
        <basic name="lowerName">
            <column name="LOWERNAME" column-definition="varchar" length="64" unique ="true" />
        </basic>
    </attributes>
</entity>

带参数null的NamedQuery
