唔系好明點解Total Price = product[1] * db_order_item.number_of_items
Hardcoded? 這個是從Databene 個shop example抽出來的...

  1. <comment>create order items</comment>
  2.         <generate type="db_order_item"
  3.                 count="{customer_count * orders_per_customer * items_per_order}" consumer="db">
  4.                 <variable name="product" source="db" selector=
  5.                      "select ean_code, price from db_product" distribution="cumulated" />
  6.                 <id name="id" generator="idGen" />
  7.                 <attribute name="number_of_items"
  8.                       min="1" max="27" distribution="cumulated" />
  9.                 <reference name="order_id" source="db"
  10.                      selector="select id from db_order where id &gt; 1" cyclic="true" />
  11.                 <reference name="product_ean_code" script="product[0]" />
  12.                 <attribute name="total_price"
  13.                       script="product[1] * db_order_item.number_of_items" />
  14.         </generate>
