What is the Hibernate version? What is the driver version? I tested your code here, on Oracle 10g, using driver version 10.0.2.2, and it worked fine :-)

Thanx for your input jpkrohling,

I am testing it in oracle 10g using hiernate 3, and driver version is 10.2.0.3.0.

Still I am facing the same problem..

Below is the detail error log.

Code:
Hibernate:
    SELECT
        p.I_COMPANY as I_COMPANY
    FROM
        P_CATALOG p

Could you please try with this mapping..

Code:
<hibernate-mapping>
  <class entity-name="testhibernateapp.Catalog" table="P_CATALOG">
    <composite-id>
      <key-property column="I_COMPANY" name="company" type="double"/>
      <key-property column="I_SEASON" name="season" type="double"/>
      <key-property column="I_CATALOG" name="catalog" type="double"/>
    </composite-id>
    <property column="S_CATALOGNAME" name="catalogname" type="string"/>
    <property column="I_CIRCULATION_ACT" name="circulationAct" type="double"/>
  </class>
  <sql-query name="catalogBySeason">
   <return class="testhibernateapp.Catalog" alias="c"/>
    SELECT p.I_COMPANY AS {c.company} FROM P_CATALOG p
  </sql-query>
</hibernate-mapping>

If I select all the column then its working fine.
Code:
<sql-query name="catalogBySeason">
   <return class="testhibernateapp.Catalog" alias="c"/>
     SELECT p.I_COMPANY ,p.I_SEASON,p.I_CATALOG,p.S_CATALOGNAME,p.I_CIRCULATION_ACT FROM P_CATALOG p
  </sql-query>


But If I miss any one of the column then its complaining.
Code:
<sql-query name="catalogBySeason">
   <return class="testhibernateapp.Catalog" alias="c"/>
     SELECT p.I_COMPANY, p.I_SEASON FROM P_CATALOG p
  </sql-query>

Code:
Hibernate:
    SELECT
        p.I_COMPANY ,
        p.I_SEASON
    FROM
        P_CATALOG p

Since you are saying

Code:
<return class="testhibernateapp.Catalog" alias="c"/>


your query needs to include all column that are needed for the Catalog entity. If you only want some of the column you should use <return-scalar> instead. See http://www.hibernate.org/hib_docs/v3/re ... eries.html for more information.
