RE: Same name property/column automapping

This has been discussed before, and so has the inverse. That is, not all
columns in the result map need be present in the db result set. The biggest
argument against this is performance, as it requires accessing the DB metadata,
possibly EVERY time a query is run. However, I don't have too much problem with
it if it is optional. I would sooner see a syntax something like:
<!-- FORCES AUTOMAP OF ALL REMAINING COLUMNS -->
<resultMap id=”get-product-result” class=”com.ibatis.example.Product”
autoMapRemaining="true">
<result property=”id”
column=”ID_THAT_NEEDS_TO_BE_REMAPPED”/>
<result property=”category” column=”categoryId” select=”getCategory”/>
</resultMap>
<!-- RELAXES REQUIREMENT THAT ALL COLUMNS MUST BE PRESENT -->
<resultMap id=”get-product-result” class=”com.ibatis.example.Product”>
<result property=”description” column=”DESC” optional="true" />
...
</resultMap>
<!-- OR -->
<resultMap id=”get-product-result” class=”com.ibatis.example.Product”
ignoreMissingColumns="true">
...
</resultMap>
