Subject RE: queryForMap returning zero results
Date Wed, 10 May 2006 06:24:37 GMT
Thanks Niels for your answer.
 
I'm affraid I haven't been completely correct in my description of the
issue. Sorry about that. queryForMap does actually return 1 (one) value, the
last row in the resultset. About accessor methods: I do have
getProductCategoryId()  and setProductCategoryId(String productCategoryId)
in ProductCategory class.
 
But why queryForMap returns only the last row from the resultset?
 
Thanks again!

That's very strange, since queryForMap() uses queryForList() internally. Is
there a proper getter in class 'com.mycompany.ecommerce.ProductCategory' for
the 'productCategoryId' property?

Hello everybody!

I'm getting zero results when using queryForMap. Whith queryForList I get
the correct results.

----- SQLMap -----
<resultMap id="listOfCategories"
class="com.mycompany.ecommerce.ProductCategory">
        <result column="product_category_id" property="productCategoryId"
jdbcType="VARCHAR" />
        <result column="parent_category_id" property="parentCategoryId"
jdbcType="VARCHAR" />
        <result column="category_name" property="categoryName"
jdbcType="VARCHAR" />
</resultMap>

<select id="listAvailableCategories" resultMap="listOfCategories">
        SELECT
              product_category_id,
              parent_category_id,
              category_name
        FROM  product_category
</select>

----- Java -----
public Map listAvailableCategories() throws SQLException {
        Map prodCatRel = sqlMapClient.queryForMap("listAvailableCategories",
null, "productCategoryId");
        return prodCatRel;
}

In the logging output I can clearly see that there are several rows in the
resultset, but prodCatRel.size()==0. 

 

Anybody have an idea? 

 

Thanks for your time!
