Less Than
The following example shows getting student records who's age less than specified value.
The attribute parameterClass="int" allows us to pass student age
as parameter which would substitute #value# in the SQL.
Since SQLMap is an XML document the symbols <, >, etc. cannot be used directly.
We need to embed such symbols inside <![CDATA[ ]]>
