Question

I am getting an error while generating a sequence for an id field in HSQLDB. The mapping file is configurated like this:

<hibernate-mapping>
    <class name="ddol.rtdb.dto.Configuration" table="RTDB_CONFIGURATION">
        <id name="id" type="int">
            <column name="CONF_ID" />
            <generator class="sequence">
                <param name="sequence">CONF_ID_SEQ</param>
            </generator>
        </id>
        <property generated="never" lazy="false" name="configurationDate"
            type="java.util.Date">
            <column name="CONF_DATE" />
        </property>

It works when I use the same mapping with oracle, but does not generate the sequence when used with HSQLDB for testing. Is there anything else I should add to the mapping?

The error I am getting when I try to insert something into the table is:

ERROR org.hibernate.util.JDBCExceptionReporter - user has no privileges or object not found: CONF_ID_SEQ

HSQLDB version is 2.2.8, Hibernate version is 3.6.10

Create the sequence(CONF_ID_SEQ – if it doesn’t exists) and make sure that you have "grant" permission for that.
Alternatively, you can create a "synonym" for the sequence and give "grant" permission for all the users or to the specific users you want to. Then it should work.

    E.g  
    Consider, You are creating Sequence as "dbauser". Now, some other "user"(who don't have access) trying to use it,  
then u will get "user has no privileges" error.  
    In that case you can use above strategy.
