       Session session = HibernateUtil.getSessionFactory().openSession();
       session.beginTransaction();
       Query query =  session.createSQLQuery("INSERT INTO "+ orderName+" VALUES ("+tableId +","+ pID+" ,"+pName +
               ","+category+","+quantity+ ","+ price+" ,"+ date+")");
        int result = query.executeUpdate();
   }

You dont seem to be setting the columns to insert your values into! when you execute an insert query you need to specify exactly which columns to insert into, like so

INSERT INTO table([column1], [column1]) VALUES(value_for_col1, value_for_col2).

Im guessing thatws why hibernate is complaining about unknown columns. just guessing from your input parameters i imagine your query will need to look like this:

Query query =  session.createSQLQuery("INSERT INTO "+ orderName+" ([orderName], [tableId], [pID], [pName], [category], [quantity], [price], [date])VALUES ("+tableId +","+ pID+" ,"+pName +
           ","+category+","+quantity+ ","+ price+" ,"+ date+")");

Also for complex queries i suggest storing them within a sql file, this just makes editing easier and makes the code a bit neater. then just load the sql file as a string.

An even easier method to save in hibernate would just be to create an entity object, (create a class then annotate with @Entity). Hibernate will then save this object for you avoiding the need for native update queries!
