Hi,

I've recently started a small project that will use Hibernate.
I use Hibernate core version 3.3.1.GA.

For testing, we will use Hsqldb in file mode.
I have two persistent classes, two mapping files and a hibernate.cfg.xml file.
However, even though I've configured Hibernate to automatically create the tables, this fails for some reason.

Here is the Hibernate configuration file:

Code:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
      
      <!--property name="connection.url">jdbc:hsqldb:mem:Test</property-->
      <property name="connection.url">jdbc:hsqldb:file:target/testdb</property>
        <!-- property name="connection.url">jdbc:hsqldb:hsql://localhost</property -->
        
        <property name="connection.username">sa</property>
        <property name="connection.password"></property>
        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.HSQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">update</property>

        <mapping resource="se/dina/myplaces/domain/Feed.hbm.xml"/>
        <mapping resource="se/dina/myplaces/domain/Place.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

As you can see, I have tried to use the database both in file mode an in in-memory mode, but with the same result. I have also set "hbm2dll" to "update" to recreate the database on each test run.
From what I understand, Hibernate tries to do exactly this, but fails somehow.
It seems that the SQL for creating the tables are misinterpretet, even though I have compared it with the HSQLDB documentation and to me, it seems correct.

Here is the complete error message:

I am stuck for the time being, and I would be very grateful for any hints and tricks that can help me get through this problem.

UPDATE: I have now changed the configuration to use MySql instead, but I get a similar problem nonetheless:

Code:

[main] INFO org.hibernate.tool.hbm2ddl.SchemaUpdate - Running hbm2ddl schema update
[main] INFO org.hibernate.tool.hbm2ddl.SchemaUpdate - fetching database metadata

[main] INFO org.hibernate.tool.hbm2ddl.DatabaseMetadata - table not found: FEEDS
[main] INFO org.hibernate.tool.hbm2ddl.DatabaseMetadata - table not found: PLACES
[main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Unsuccessful: create table FEEDS (FEED_ID varchar(255) not null auto_increment, URL varchar(255), placeId varchar(255) not null, primary key (FEED_ID)) ENGINE=InnoDB
[main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Incorrect column specifier for column 'FEED_ID'
[main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Unsuccessful: create table PLACES (NATIVE_PLACE_ID varchar(255) not null auto_increment, placeId varchar(255), title varchar(255), primary key (NATIVE_PLACE_ID)) ENGINE=InnoDB
[main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Incorrect column specifier for column 'NATIVE_PLACE_ID'
[main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Unsuccessful: alter table FEEDS add index FK3FAD6754FD7B (placeId), add constraint FK3FAD6754FD7B foreign key (placeId) references PLACES (NATIVE_PLACE_ID)

So obviously there is something wrong with my configuration or code.

Thanks in advance,
Anders

I solved the problem now, I post it here if anyone runs into the same issue.

The fault was my own, I had used a String in my Java-class as id, and try to use auto-increment on a string, instead of on an integer. Simple as that.

Peace out.

Hello ,
Can you tell me how you solved this problem ?
My id has the correct type and the problem stays the same.

Thanks for answering.
