JPetStore 源代码部署的问题
最近在用iBATIS ，下载了 http://apache.freelamp.com//ibatis/binaries/ibatis.java/JPetStore-5.0.zip 学习。用源代码部署，我用的是MySql数据库。测试发现有如下bug：

主要是 src\com\ibatis\jpetstore\persistence\sqlmapdao\sql\Item.xml 数据查询有问题。
修改一处查询语句就可以了：
<select id="getItem" resultparametercacheModel="quantityCache">
select
I.ITEMID,
LISTPRICE,
UNITCOST,
SUPPLIER AS supplierId,
I.PRODUCTID AS "product.productId",
NAME AS "product.name",
DESCN AS "product.description",
CATEGORY AS "product.categoryId",
STATUS,
ATTR1 AS attribute1,
ATTR2 AS attribute2,
ATTR3 AS attribute3,
ATTR4 AS attribute4,
ATTR5 AS attribute5,
QTY AS quantity
from ITEM I, INVENTORY V, PRODUCT P
where P.PRODUCTID = I.PRODUCTID
and I.ITEMID = V.ITEMID
and I.ITEMID = #value#
</select>
