Example 26 from DevGuide.pdf explains the nullValue attribute:

<resultMap id=”get-product-result” class=”product”>
 <result property=”id” column=”PRD_ID”/>
 <result property=”description” column=”PRD_DESCRIPTION”/>
 <result property=”subCode” column=”PRD_SUB_CODE”
 nullValue=”-9999”/>
</resultMap>

Is it possible to set nullValue to string.Empty? I've tried "" but
nullValue seems to be ignored unless its length is greater than zero.

This may be unrelated, but I noticed this line in one of the other XML
files:

<parameter property="Date" nullValue="01/01/0001 00:00:00" />

I thought that I could someone solve the constant problem by defining
the .Net 1.1 constants in a properties files somewhere:

<!-- simulate .Net 1.1 constants -->
<add key="DateTime.MinValue" value="01/01/0001 00:00:00" />

Then in the other file do:

<parameter property="Date" nullValue="${DateTime.MinValue}" />

That still doesn't explain how to express string.Empty...

Thanks,
Ron
