Support HAVING in XML queries

Browse source 
GROUP BY에 사용되는 <groups> 태그 안에 <having> 태그를 넣을 수 있습니다.
문법은 <conditions> 부분에 적용되는 것과 같습니다.

<query id="queryId" action="select">
    ...
    <groups>
        <group column="document_srl" />
        <having>
            <condition operation="more" column="document_srl" var="myvar" default="0" />
        </having>
    </groups>
    ...
</query>

결과: SELECT ... GROUP BY document_srl HAVING document_srl >= 0
