iBatis中使用动态查询

iBatis中的动态查询还是比较好用的

如果想深入学习，可以参考 Manning.iBATIS.in.Action.Jan.2007

下面给出几个例子和dtd定义：

<select >
     INIT_DATE = #kfi.initDate#
    </isNotNull>
   </dynamic>
</select>


<update >
     REJECT_REASON = #rejectReason#
    </isNotNull>                       
   </dynamic>
   where
    KEY_FLOW_ID =#keyFlowId#
</update>

让iBatis中的insert返回主键 [ibatis insert 返回 自增主键]

iBatis SQL-map 文件书写注意事项

 

http://ibatis.apache.org/dtd/sql-map-2.dtd 中有<dynamic>的定义
