注意:如果<isNotEmpty>是寫在一行的話,并且是第一個的話
<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
<update id="updateRole" parameterClass="com.mmblue.model.Role"> <![CDATA[ UPDATE role SET gmt_modified = to_date(#gmtModified#,'yyyy-mm-dd hh34:mi:ss'), modifier = #modifier# ]]> <dynamic> <isNotEmpty property="isDeleted" prepend=","> <![CDATA[ is_deleted = #isDeleted# ]]> </isNotEmpty> <isNotEmpty property="roleCode" prepend=","> <![CDATA[ role_code = #roleCode# ]]> </isNotEmpty> <isNotEmpty property="roleName" prepend=","> <![CDATA[ role_name = #roleName# ]]> </isNotEmpty> <isNotEmpty property="deptId" prepend=","> <![CDATA[ dept_id = #deptId# ]]> </isNotEmpty> </dynamic> <![CDATA[ WHERE id = #id# ]]> </update>
2.再來個全部遍歷的
<update id="updateUser" parameterClass="com.mmblue.domain.User"> UPDATE MYIVR_TUSER <dynamic prepend="SET "> <isNotEmpty property="realName" prepend=","><![CDATA[ REALNAME = #realName# ]]></isNotEmpty> <isNotEmpty property="password" prepend=","><![CDATA[ PASSWORD = #password# ]]></isNotEmpty> <isNotEmpty property="projectId" prepend=","><![CDATA[ PROJECT_ID = #projectId# ]]></isNotEmpty> <isNotEmpty property="isEable" prepend=","><![CDATA[ ISENABLE = #isEable# ]]></isNotEmpty> <isNotEmpty property="createTime" prepend=","><![CDATA[ CREATETIME = #createTime# ]]></isNotEmpty> <isNotEmpty property="name" prepend=","><![CDATA[ USERNAME = #name# ]]></isNotEmpty> <isNotEmpty property="id" prepend=","><![CDATA[ USERID = #id# ]]></isNotEmpty> <isNotEmpty property="isFirstLogin" prepend=","><![CDATA[ ISFIRSTLOGIN = #isFirstLogin# ]]></isNotEmpty> </dynamic> <dynamic prepend="WHERE"> USERID = #id# </dynamic> </update>
