ibatis中动态SQL_update

如何知道上一篇的动态INSERT的话，动态UPDATE就很简单了，直接上XML

注意：如果是写在一行的话，并且是第一个的话

内容注意中间加个空格，不然会出现 update role setname=xxx 直接报错

 <update id="updateRole" parameterClass="com.mmblue.model.Role">

         UPDATE role
         SET
             gmt_modified = to_date(#gmtModified#,'yyyy-mm-dd hh24:mi:ss'),
             modifier = #modifier#
     ]]>
         <dynamic>
             <isNotEmpty property="isDeleted" prepend=",">

                     is_deleted = #isDeleted#
                 ]]>
             isNotEmpty>
             <isNotEmpty property="roleCode" prepend=",">

                     role_code = #roleCode#
                 ]]>
             isNotEmpty>
             <isNotEmpty property="roleName" prepend=",">

                     role_name = #roleName#
                 ]]>
             isNotEmpty>
             <isNotEmpty property="deptId" prepend=",">

                     dept_id = #deptId#
                 ]]>
             isNotEmpty>
         dynamic>

         WHERE id = #id#
     ]]>
 update>

 

 

2.再来个全部遍历的

 <update id="updateUser" parameterClass="com.mmblue.domain.User">
     UPDATE MYIVR_TUSER
     <dynamic prepend="SET ">
                 <isNotEmpty property="realName" prepend=",">isNotEmpty>
                 <isNotEmpty property="password" prepend=",">isNotEmpty>
                 <isNotEmpty property="projectId" prepend=",">isNotEmpty>
                 <isNotEmpty property="isEable" prepend=",">isNotEmpty>
                 <isNotEmpty property="createTime" prepend=",">isNotEmpty>
                 <isNotEmpty property="name" prepend=",">isNotEmpty>
                 <isNotEmpty property="id" prepend=",">isNotEmpty>
                 <isNotEmpty property="isFirstLogin" prepend=",">isNotEmpty>
     dynamic>
     <dynamic prepend="WHERE">
         USERID = #id#
     dynamic>
 update>
