2.支持嵌套

 ﹤isNotNull  property ="id" ﹥              
   ﹤!--  isGreaterThan判断参数是否大于compareValue,isGreaterEquals是大于等于  --﹥      
       ﹤isGreaterThan  prepend =" and "  property ="id"  compareValue ="0" ﹥                                        id = #id#                
      </isGreaterThan ﹥ 
﹤/isNotNull﹥

3.in 的用法 in(1,1,2)

<dynamic prepend="WHERE">
   <isNotNull prepend="AND" property="emailAddress">
 ACC_EMAIL = #emailAddress#
 </isNotNull>
 <isNotNull property="idList" prepend=" or ACC_ID in ">
     <iterate property="idList" conjunction="," open="(" close=")" >
  #id#
    </iterate>
  </isNotNull>
</dynamic>

4. iBATIS动态查询几个常用属性:

  ﹤isPropertyAvailable﹥:  属性是存在
  ﹤isNotPropertyAvailable﹥:  属性不存在
  ﹤isNull﹥:  属性值是null
  ﹤isEmpty﹥:  判断Collection.size ﹤ 1 或String.length()﹤1
  ﹤isEqual﹥:  等于
  ﹤isNotEqual﹥:  不等于
  ﹤isGreaterThan﹥:  大于
  ﹤isGreaterEqual﹥:  大于等于
  ﹤isLessThan﹥:  小于
  ﹤isLessEqual﹥:  小于等于
