hibernate h2 embeddable list expected "identifier"

Related searches

I'm trying to associate a list of function (whom Embeddable) within my Employee Entity and H2 seems unhappy with this saying that it expected an "identifier"

Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement " CREATE TABLE EMPLOYEE_FUNCTIONS ( EMPLOYEE_EMPLOYEEID VARCHAR(255) NOT NULL, ACTIVE BOOLEAN NOT NULL, DEPARTMENTNUMBER INTEGER NOT NULL, DESCRIPTION VARCHAR(255), ORDER[*] INTEGER NOT NULL ) "; expected "identifier";

The thing is I already done that with an other project and I don't see why it doesn't work.

Employee.java

@Entity
public class Employee extends AbstractScheduleEntity<EmployeeSchedule> {
    public static final String ACOMBA_UNIQUE_FIELD = "acombaUnique";

    @Id
    @GenericGenerator(name = "sequence_id", strategy = 
    "ca.tecsar.core.sql.ServerSequenceGenerator")
    @GeneratedValue(generator = "sequence_id")
    @Column(name = "EmployeeID", unique = true, nullable = false)
    private String employeeID;
    @ElementCollection
    private List<Function> functions;

    //getter and setter
}

Function.java

@Embeddable
public class Function implements Serializable {
    private int order;
    private boolean active;
    private String description;
    private int departmentNumber;

    //getter and setter
}

I removed a few properties in Employee that wasn't necessary. What may cause this error? Is it because I have a String as identifier in my Employee? If so how can I tell to Hibernate to add Employee_EmployeeID as identifier? Thanks

Turns out I was being dumb and named a column "Order". Wonder why H2 wasn't happy :upside_down:

Changed the variable name to something else and it worked!

I had the same problem with Spring and H2 database for tests, My entity had the field name "interval", I renamed to "inter" and resolved the problem.

So, these errors happen due to a sql reserved names in entities.

Fix — org.h2.jdbc.JdbcSQLException: Schema not found — And , H2 is supposed to create the schema automatically but anyways. (By default, if the database specified in the embedded URL does not yet exist, using some hibernate.ddl-auto=create or spring.jpa.hibernate.ddl-auto=create. So that the above schema-{platform}.sql files will be executed as expected. So I searched for a way to do this and I found that I shall configure a hibernate connection URL which I tried like this. props.put("hibernate.connection.url", "jdbc:h2:~/test"); in my HibernateConfiguration.java. Without success though, no errors but also nothing saved, and I did not find that test file that should be created from that URL.

try to put the ; before the " and test ?

What's wrong? If you are new to hibernate you can read my Spring Hibernate tutorial. Introduction to H2 Database. H2 is an open source embedded database built on java ships in a single .jar file. Therefore you can easily embed h2 database into your application. H2 Database has a built in web based console that you can use to interact with the database.

So far, only very few tests have been run, and everything seems to work as expected . One entity can be embedded in another entity. The attributes of an entity can be common attributes of more than one entity. In this case there can be one embeddable entity. And this embeddable entity can be embedded in more than one entity. Let's understand by example. We have one Animal entity, it has name and location attributes.

hibernate h2 embeddable list expected “identifier” I'm trying to associate a list of function (whom Embeddable) within my Employee Entity and H2 seems unhappy with this saying that it expected an "identifier" Caused by: org.h2.jdbc.JdbcSQLException:

The Entity and the embeddable collection are mapped to two separate foreign/primary-key tables. One for the entity and other for embeddable fields/properties values. The collection table has the foreign key pointing to the primary key of the entity. This is similar to OneToMany, except the target is an embeddable class instead of another entity.

Comments
  • ORDER is a reserved keyword for H2DB - h2database.com/html/advanced.html#compatibility
  • Yes I understood that.
  • @Enumerated(EnumType.ORDINAL) private RaceGroup group GROUPalso causes same problem. :P
  • I also run into this problem but in my case reserved word was offset. Renaming column helped.
  • Exactly my case, I had from and until dates, that broke my query. Renaming them to fromDate and untilDate solved the issue.
  • The query is generated by Hibernate not me
