如何知道上一篇的動態INSERT的話，動態UPDATE就很簡單了，直接上XML

注意：如果<isNotEmpty>是寫在一行的話，並且是第一個的話

<isNotEmpty property="realName" prepend=","><![CDATA[ REALNAME = #realName# ]]></isNotEmpty>

內容注意中間加個空格，不然會出現 update role setname=xxx 直接報錯

1. <update id="updateRole" parameterClass="com.mmblue.model.Role"
   >  
2.     <![CDATA[ 
3.         UPDATE role 
4.         SET 
5.             gmt_modified = to_date(#gmtModified#,'yyyy-mm-dd hh24:mi:ss'), 
6.             modifier = #modifier# 
7.     ]]>  
8.         <dynamic>  
9.             <isNotEmpty property="isDeleted" prepend=",">  
10.                 <![CDATA[
     
11.                     is_deleted = #isDeleted# 
12.                 ]]>  
13.             </isNotEmpty>  
14.             <isNotEmpty property="roleCode" prepend=",">  
15.                 <![CDATA[  
16.                     role_code = #roleCode# 
17.                 ]]>  
18.             </isNotEmpty>
      
19.             <isNotEmpty property="roleName" prepend=",">  
20.                 <![CDATA[  
21.                     role_name = #roleName# 
22.                 ]]>  
23.             </isNotEmpty>  
24.             <isNotEmpty property="deptId" prepend=",">  
25.                 <![CDATA[  
26.                     dept_id = #deptId# 
27.                 ]]>  
28.             </isNotEmpty>  
29.         </dynamic>  
30.     <![CDATA[ 
31.         WHERE id = #id# 
32.     ]]>  
33. </update>  

2.再來個全部遍歷的

1. <update id="updateUser" parameterClass="com.mmblue.domain.User">  
2.     UPDATE MYIVR_TUSER  
3.     <dynamic prepend="SET ">  
4.                 <isNotEmpty property="realName" prepend=","><![CDATA[ REALNAME = #realName# ]]></isNotEmpty>  
5.                 <isNotEmpty property="password" prepend=","><![CDATA[ PASSWORD = #password# ]]></isNotEmpty>  
6.                 <isNotEmpty property="projectId" prepend=","><![CDATA[ PROJECT_ID = #projectId# ]]></isNotEmpty>  
7.                 <isNotEmpty property="isEable" prepend=","><![CDATA[ ISENABLE = #isEable# ]]></isNotEmpty>  
8.                 <isNotEmpty property="createTime" prepend=","><![CDATA[ CREATETIME = #createTime# ]]></isNotEmpty>  
9.                 <isNotEmpty property="name" prepend=","><![CDATA[ USERNAME = #name# ]]></isNotEmpty>  
10.                 <isNotEmpty property="id" prepend=","><![CDATA[ USERID = #id# ]]></isNotEmpty>  
11.                 <isNotEmpty property="isFirstLogin" prepend=","><![CDATA[ ISFIRSTLOGIN = #isFirstLogin# ]]></isNotEmpty>  
12.     </dynamic>  
13.     <dynamic prepend="WHERE">  
14.         USERID = #id#  
15.     </dynamic>  
16. </update>
