Examples of QueryChain

org.apache.cayenne.query.QueryChain
A Query decorator for a collection of other queries. Note that QueryChain will always return DataRows (that is if it returns data), as it has no way of knowing how to convert the results to objects. @since 1.2

Examples of org.apache.cayenne.query.QueryChain


    public void testRefreshingToOne() {


        ObjectContext context = createDataContext();


        QueryChain chain = new QueryChain();
        chain.addQuery(new SQLTemplate(
                Artist.class,
                "INSERT INTO ARTIST (ARTIST_ID, ARTIST_NAME) VALUES (1, 'a1')"));
        chain
                .addQuery(new SQLTemplate(
                        Painting.class,
                        "INSERT INTO PAINTING (PAINTING_ID, ARTIST_ID, PAINTING_TITLE) VALUES (1, 1, 'p1')"));


        context.performQuery(chain);
