Using a NamedQuery with a composite class

Question

I have the following class defined in my mapping XML file:

<class name="com.data.StateRefData" table="STATE_REF">
   <composite-id name="primaryKey" class="com.data.StateRefPkData">
       <key-property name="countryCode">
           <column name="COUNTRY_CODE"  />
        </key-property>

        <key-property name="state">
            <column name="STATE"  />
        </key-property>
    </composite-id>

   <property name="dialingCode" column="DIALING_CODE"></property>
   <property name="isActive" column="IS_ACTIVE"></property>
   <property name="localeCode" column="LOCALE_CODE"></property>
   <property name="stName" column="ST_NAME"></property>
</class> 

I am trying to define a NameQuery for this class. What I tried was:

<query name="findState">
    <![CDATA[ from
      com.data.StateRefData
        WHERE primaryKey = :primaryKey
    ]]>
 </query> 

The Java code that I use to call this is:

Query stateQuery = null;
List<StateRefData> stateList = null;
StateRefPkData primaryKey = new StateRefPkData();
StateRefData filter = new StateRefData();

primaryKey.setCountryCode(inCountryCode);
primaryKey.setState(inStateProvince);
filter.setPrimaryKey(primaryKey);

stateQuery = session.getNamedQuery("findState");
stateQuery.setProperties(filter);

However, I get these errors right at the "stateQuery.list()" part:

[ERROR JDBCExceptionReporter:72] Line 1: Incorrect syntax near ','.
org.hibernate.exception.SQLGrammarException: could not execute query

        at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:59)

   at org.hibernate.impl.SessionImpl.list(SessionImpl.java:844)
   at org.hibernate.impl.QueryImpl.list(QueryImpl.java:74) 

Any idea on how to use a NamedQuery with a composite?

Note: I have also tried doing:

stateQuery.setParameter("primaryKey", primaryKey);

and it still has the error.

New (edited): Here is the HQL and SQL that happens when I execute the code:

Solution

Can you provide the SQL code that is being generated by turning on SQL logging?

Here is a sample if you were using log4j.properties:

log4j.logger.org.hibernate.SQL=DEBUG

UPDATE #1

I am not sure why the existing query does not work, but you should also give this a try. No need to update any other code as passing a POJO should automatically bind the getters to the named parameters.

<query name="findState">
    <![CDATA[ from
      com.data.StateRefData
        WHERE primaryKey.countryCode = :countryCode AND primaryKey.state = :state
    ]]>
</query>

OTHER TIPS

Is there a chance that inCountryCode or inStateProvince is empty or null?
