Examples of com.mysql.clusterj.Query

com.mysql.clusterj.Query
A Query instance represents a specific query with bound parameters. The instance is created by the method {@link com.mysql.clusterj.Session#createQuery}.

        // compare the column with the parameter
        Predicate compare = column.equal(param);
        // set the where clause into the query 
        dobj.where(compare);
        // create a query instance
        Query query = session.createQuery(dobj);


        // set the parameter value
        query.setParameter("eid", (long)8);
        // get the results
        List<Dn2id> results = query.getResultList();
        // consistency check the results
        consistencyCheck(results);
        Set<Long> expected = new HashSet<Long>();
        expected.add((long)8);
        Set<Long> actual = new HashSet<Long>();
