iBATIS: Extending Your ResultMap

Here is an useful feature of the ResultMap.

In your iBATIS ResultMap, the optional extends attribute can be set to the name of another parameterMap upon which to base this parameterMap. All properties of the super parameterMap will be included as part of this parameterMap, and values from the super parameterMap are set before any values specified by this parameterMap. The effect is similar to extending a class

<resultMap id=”resultMapName” 
[groupBy=“some property list”]> 
<result property=”propertyName” column=”COLUMN_NAME” 
[columnIndex=”1”] [javaType=”int”] [jdbcType=”NUMERIC”]
[nullValue=”-999999”] [select=”someOtherStatement”]
