> SQLMap statements allow for dynamic select clauses, but currently, it is impossible to create dynamic result maps. For example:
> <select id="dynamicSelect" parameterClass="java.util.Map" resultClass="java.util.HashMap"> 
> SELECT 
> <isPropertyAvailable property="countQuery"> 
> count(*) 
> </isPropertyAvailable> 
> <isNotPropertyAvailable property="countQuery"> 
> A, B, C 
> </isNotPropertyAvailable> 
> FROM [...] 
> </select>
> This construct is legal, but will break upon execution.
> It seems odd to have the ability to create dynamic select statements but not have the ability to actually use them (without polluting the statement with "NULL AS"). This issue is bound to come up often...
