oracle xml文件基本插入写法

<mapper namespace="com.keyou.dao.samSystem.SamApplyDao">
<insert id="insertSamApplyApproval">
        INSERT INTO SAM_APPLYAPPROVAL
        <trim prefix="(" suffix=")" suffixOverrides=",">

        </trim>
    </insert>
    </mapper>

namespace与dao接口联系
id与接口中方法名映射
samApplyApproval入参与dao接口方法中的@param指定的参数映射如

 void insertSamApplyApproval(@Param("samApplyApproval")SamApplyApproval samApplyApproval);
