> In Ibatis using sqlMaps, we are able to do embedded resultMaps within
> resultMaps. If we have one resultMap with only one result that is a
> resultMap (ie <result property="userAbsence"
> resultMap="User.UserAbsenceResult"/> )then using the groupby attribute has
> the effect of grouping by that property.
> However, if we have one resultMap that has multiple results that are
> resultMap then the group by only works for the first embedded item.
> Below is a working code snippet that uses embedded resultMaps. Adding the
> groupby attribute forces the class that is returned to only return one item
> per groupby key.

> Planning to get around this by creating separate SQLs for the userAbesence
> and the userSkill. Since we are only expecting 1 userID at a time we don't
> expect much overhead, then from the individual sqls for userSkill and
> userAbsence I can do the group by within the query. Does anyone have any
> other suggestions?
