SequenceGenerator problem with unit testing in Hsqldb/H2

Question

I have tried using both Hsqldb and H2 for unit testing but facing problem with sequence generators. Field declaration looks like this.

@Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="keyword_seq")
@SequenceGenerator(name="keyword_seq",sequenceName="KEYWORD_ID_SEQ", allocationSize=1)
@Column(name="IM_KEYWORD_ID")
private Long keywordId;

When I try to test simple insert in this table in Hsqldb with following configuration, it gives error

<prop key="hibernate.connection.driver_class">org.hsqldb.jdbc.JDBCDriver</prop>
<prop key="hibernate.connection.url">jdbc:hsqldb:mem:testdb;sql.syntax_ora=true</prop>

Error :

   Caused by: java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: KEYWORD_ID_SEQ.NEXTVAL
        at org.hsqldb.jdbc.Util.sqlException(Unknown Source)
        at org.hsqldb.jdbc.Util.sqlException(Unknown Source)

With H2:

<prop key="hibernate.connection.driver_class">org.h2.Driver</prop>
<prop key="hibernate.connection.url">jdbc:h2:~/test</prop>

Error is :

Hibernate: select KEYWORD_ID_SEQ.nextval from dual
3085 [main] WARN org.hibernate.util.JDBCExceptionReporter  - SQL Error: 42001, SQLState: 42001
3088 [main] ERROR org.hibernate.util.JDBCExceptionReporter  - Syntax error in SQL statement "SELECT KEYWORD_ID_SEQ.NEXTVAL FROM[*] DUAL "; expected "identifier"; SQL statement:

Any idea, how to solve this?

Solution

I think the dialect is set wrongly. Can you check your hibernate configuration.
