What version of Hibernate libraries do you have on your project where you are trying to run this HQL query?

Also I’m assuming this project has Hibernate Capabilities added to it?

[Haris Peco]

mepegomiabuelitoayer ,

Can you send more details :

– as Riyad says, what version hibernate you use
– your mappings, POJO and HQL query

I suppose that you have type mismatch in POJO and mappings

Hi, thanks for your support javascript:emoticon(‘:)’)
Smile.

support-rkalla :

Im using Hibernate 3.1 Core Libraries and Advanced Support Libraries, I tried to run with HQL query and deployed with JBoss and i got the same exception.

support-snpe:

Im running the SDK 1.5, working with Postgres 8.0, postgresql-8.2dev-503.jdbc3.jar, and Im using a hibernate Reverse Engineering, im using views.

<hibernate-reverse-engineering>
    <type-mapping>
        <sql-type jdbc-type="VARCHAR" hibernate-type="java.lang.String" />
        <sql-type jdbc-type="INTEGER" hibernate-type="java.lang.Long" />
        <sql-type jdbc-type="TIME" hibernate-type="java.sql.Time" />
        <sql-type jdbc-type="DATE" hibernate-type="java.util.Date" />

    </table>
<!-- FOR VIEWS -->

    </table>

🙂

I appreciate your attention,i hope this information helps to solve my problem.

[mepegomiabuelitoayer]

The problem was that my database had an attribute called version, and the MyEclipse Hibernate Tool put <version> tag instead <property>.

Bad AutoGenerated Mapping:

 <version name="version" type="java.lang.String" column="version" />

Change To:

 <property name="version" type="java.lang.String">
            <column name="version" length="05" not-null="true" />
        </property>

😀 Thanks for your Help.

You can control if MyEclipse will generate version/timestamp column on page 2 of wizard : ‘Generate version and timestamp tags’
