iBatis中使用動態查詢

iBatis中的動態查詢還是比較好用的
如果想深入學習，可以參考 Manning.iBATIS.in.Action.Jan.2007
下面給出幾個例子和dtd定義：
<select id="selectDispatchedKey" parameterClass="KeyAndKeyFlowInfo" resultMap="KeyAndKeyFlowResult">
select distinct
KEY_ID,
USER_ID,
INITIATOR,
INIT_DATE,
INITIATOR_EMAIL,
SGS_KEY.BRANCH_NAME,
APPROVER,
APPROVER_EMAIL,
APPROVE_DATE
from
SGS_KEY,
SGS_KEY_FLOW
where SGS_KEY.APPLY_FLOW_ID=SGS_KEY_FLOW.KEY_FLOW_ID
<dynamic prepend="and" open="(" close=")">
<isNotNull property="ki.userId" prepend="and" removeFirstPrepend="false">
USER_ID = #ki.userId#
</isNotNull>
<isNotNull property="kfi.initiator" prepend="and">
INITIATOR = #kfi.initiator#
</isNotNull>
<isNotNull property="kfi.initDate" prepend="and">
INIT_DATE = #kfi.initDate#
</isNotNull>
</dynamic>
</select>

<update id="updateKeyFlow" parameterClass="KeyFlowInfo">
update SGS_KEY_FLOW set
<dynamic>
KEY_FLOW_ID =#keyFlowId#
<isNotNull property="branchName" prepend=",">
BRANCH_NAME = #branchName#
</isNotNull>
<isNotEqual property="operation" prepend="," compareProperty="operation" compareValue="0">
OPERATION = #operation#
</isNotEqual>
<isNotNull property="initiator" prepend=",">
INITIATOR = #initiator#
</isNotNull>
<isNotNull property="initiatorEmail" prepend=",">
INITIATOR_EMAIL = #initiatorEmail#
</isNotNull>
<isNotNull property="initDate" prepend=",">
INIT_DATE = #initDate#
</isNotNull>
<isNotNull property="approver" prepend=",">
APPROVER = #approver#
</isNotNull>
<isNotNull property="approverEmail" prepend=",">
APPROVER_EMAIL = #approverEmail#
</isNotNull>
<isNotNull property="approveDate" prepend=",">
APPROVE_DATE = #approveDate#
</isNotNull>
<isNotEqual property="keyNum" prepend="," compareProperty="keyNum" compareValue="0">
KEY_NUM = #keyNum#
</isNotEqual>
<isNotNull property="applyReason" prepend=",">
APPLY_REASON = #applyReason#
</isNotNull>
<isNotNull property="rejectReason" prepend=",">
REJECT_REASON = #rejectReason#
</isNotNull>
</dynamic>
where
KEY_FLOW_ID =#keyFlowId#
</update>
