java - QueryParameterException even if everything seems to be named properly

Question

I'm debugging the following function:

public List<ImpPeriode> importPeriode(Integer type, Date dateDebut) {
    String sQuery = "from "+ImpPeriode.class.getCanonicalName()+" ip where ip.type = :type and ip.dateDebut > :dateDebut";
    Query query =  getSession()
            .createQuery(sQuery)
            .setParameter("type", type)
            .setParameter("dateDebut", dateDebut);
    return (List<ImpPeriode>) query.list();
}

The mapping for my ImpPeriode class is:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping schema="importeloi">
    <class name="com.an.eloi.model.domaine.importation.ImpPeriode" table="imp_periode">
        <id name="id" type="java.lang.Integer">
            <column name="periode_id" />
        </id>

        <property name="type" type="java.lang.Integer">
            <column name="periode_type" not-null="true"/>
        </property>

        <property name="dateDebut" type="java.util.Date">
            <column name="periode_datedeb" length="19" not-null="true"/>
        </property>

        <property name="dateFin" type="java.util.Date">
            <column name="periode_datefin" length="19" not-null="true"/>
        </property>

    </class>
</hibernate-mapping>

but somehow, I keep getting an error indicating an error in my parameter naming:

org.hibernate.QueryParameterException: could not locate named parameter [type]

I'm using Java 7 and Hibernate 3.6.10.

Obviously I'm missing something, but what?

Edit:

I changed the code in order to make the word "type" disappear:

public List<ImpPeriode> importPeriode(Integer periodeType, Date periodeDateDebut) {
    String sQuery = "from "+ImpPeriode.class.getCanonicalName()+" ip where ip.periodeType = :periodeType and ip.periodeDateDebut > :periodeDateDebut";
    Query query =  getSession()
            .createQuery(sQuery)
            .setParameter("periodeType", periodeType)
            .setParameter("periodeDateDebut", periodeDateDebut);
    return (List<ImpPeriode>) query.list();
}

and

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping schema="importeloi">
    <class name="com.an.eloi.model.domaine.importation.ImpPeriode" table="imp_periode">
        <id name="periodeId" type="java.lang.Integer">
            <column name="periode_id" />
        </id>

        <property name="periodeType" type="java.lang.Integer">
            <column name="periode_type" not-null="true"/>
        </property>

        <property name="periodeDateDebut" type="java.util.Date">
            <column name="periode_datedeb" length="19" not-null="true"/>
        </property>

        <property name="periodeDateFin" type="java.util.Date">
            <column name="periode_datefin" length="19" not-null="true"/>
        </property>

    </class>
</hibernate-mapping>

Sadly, I get exaclty the same error.

类型是 HQL 中的保留字。如果您重命名您的字段，它应该可以工作。
