>             Project: Hibernate3
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.2.4
>         Environment: Hibernate 3.2.4GA
> MySQL 4.0.20-standard 
>            Reporter: Anthony Tam

> I have downloaded the HelloWorld example and try to use Hibernate. I have changed the persistence.xml to use the MySQL database. The configuration I changed are
> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
> <property name="hibernate.connection.url" value="jdbc:mysql://(mysql database)" />
>    <property name="hibernate.connection.username" value="username" />
>    <property name="hibernate.connection.password" value="password" />
>  <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
> When I am using the Hibernate core shipped with the example, that is version 3.2.0.cr5, it works totally fine. After that, I download the latest Hibernate core from your website and replace the hibernate3.jar with the latest one, I encounter the an error when I try to presist the Message object into the database.
> The error is a SQLError bounced from MySQL saying that the field of ID is not supplied. When I turn on the SQL debug, I found that in version 3.2.0.cr5, the ID field is set to NULL and in version 3.2.4GA, the ID field is ?.
> I can figure a work around to tempory fix this issue, I use the annotation
> @org.hibernate.annotations.Entity(
> 	dynamicInsert = true
> )
> to ask hibernate to dunamic generate the SQL statment and then the ID field will not be supplied in the insert SQL.
