Greater Than
The following example shows getting student records who's age greater 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[ ]]>
01<?xml version="1.0" encoding="UTF-8"?>

11 STUDENT_ID as studentId,
12 FIRST_NAME as firstName,
13 LAST_NAME as lastName,
