Re: [eclipselink-users] soundex query..

If Categories is an entity then you can use jpql:
entityManager.createQuery("SELECT c.category, c.first_name FROM Categories c WHERE FUNC('SOUNDEX', c.category) = FUNC('SOUNDEX', categoryName)");

    Good Afternoon Eclipselink users,

    I am trying to use soundex with eclipselink and am running into some

    This is the query that i want to do

    SELECT category, first_name
    FROM categories
    WHERE SOUNDEX(category)
    = SOUNDEX('subscriber');

    Following is the code I have
    public Category getCategoryBasedOnName(categoryName)
         ReadAllQuery raq = new ReadAllQuery(Categories.class);
         ExpressionBuilder builder = raq.getExpressionBuilder();
         Expression fnExp =
         Expression valExp =
         ReadObjectQuery query = new ReadObjectQuery(Categories.class,
    valExp );
         Query jpaq = JpaHelper.createQuery(query, getEntityManager()) ;
         return jpaq ;

    Following is the exception that i am getting..

    cannot be cast to

    I don't know what i am doing wrong here.. I am able to set the fnExp
    properly. The problem i am having is with setting the soundex on a
    string value. How do I do it properly?

    Alternatively, how do i set the valExp properly in the above
    example. There are some old toplink examples that uses namedquery
    but i would prefer to do it with Expressions and ReadObject/ReadAll
    queries .. Please point me to some examples that use soundex and are
    eclipselink specific .
