Supplying a CTE in fromValues() results in exception

[Mobe91]

This happens because the CTE subselect is used as table name in com.blazebit.persistence.impl.hibernate.HibernateJpaProvider#getColumnType:194.

[Mobe91]

Easiest fix is to add

if (t.getSubselect() != null) {
    map.put("( " + t.getSubselect() + " )", t);
    Iterator<Column> columnIter = t.getColumnIterator();
    while (columnIter.hasNext()) {
           final Column column = columnIter.next();
           // populate column sql type
           column.getSqlType(dialect, mapping);
    }
}

to com.blazebit.persistence.impl.hibernate.SimpleDatabase.
We also need to supply org.hibernate.dialect.Dialect and org.hibernate.engine.spi.Mapping to com.blazebit.persistence.impl.hibernate.SimpleDatabase.
