Oracle + MyBatis 3 实现批量新增/修改

批量新增Mapper 定义

public interface BaseHouseMapper {
    // 批量新增Mapper 定义
    void batchInsert(@Param("list") List<BaseHouse> list);
    // 批量修改Mapper 定义
    void batchUpdate(@Param("list") List<BaseHouse> list);
}

XML 定义

<insert id="batchInsert" paramterType ="java.util.List">
    insert into BASE_HOUSE(BIZ_ID, PROJECT_ID, BUILDING_ID, ******)
        <foreach collection="list" item ="item" index = "index" separator="union all">
         select #{item.bizId}, #{item.projectId}, #{item.buildingId}, ****** from dual
        </foreach>
</insert>

<update id="batchUpdate" paramterType ="java.util.List">
    <foreach collection="list" item ="item" index = "index" open ="begin" close=";end;"             separator=",">
     update BASE_HOUSE
        set
        PROJECT_ID = #{item.projectId},
        BUILDING_ID = #{item.buildingId},
        ******
        where BIZ_ID = #{item.bizId}
    </foreach>
</update>

拓展:Oracle + MyBatis 3另一种批量插入方法。

    <insert id="batchInsert" parameterType="java.util.List">
        INSERT ALL
        <foreach item="item" index="index" collection="list">
        INTO BASE_HOUSE
        (
            BIZ_ID,
            PROJECT_ID,
            BUILDING_ID,
            ******
        ) VALUES
        (
            #{item.bizId},
            #{item.projectId},
            #{item.buildingId},
            ******
        )
        </foreach>
        SELECT 1 FROM DUAL
    </insert>
