MyBatis中批量insert

在orcale和mybatis执行批量插入是不一样的。

orcale如下:(这里要注意的是:useGeneratedKeys="false" )

方式1:oracle批量插入使用 insert all into table(...) values(...) into table(...) values(...) select  1  from dual; 

<insert id="insertListBatch" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT ALL
        <foreach item="item" index="index" collection="list">
        INTO student
        (
            ID,
            name,
            age,
            sex,
            CREATE_TIME
        ) VALUES
        (
            #{item.id, jdbcType=NUMERIC},
            #{item.name, jdbcType=VARCHAR},
            #{item.age, jdbcType=VARCHAR},
            #{item.sex, jdbcType=VARCHAR},
            #{item.createdTime, jdbcType=NUMERIC} 
        )
        </foreach>
        SELECT 1 FROM DUAL
    </insert>

方式2: insert into table(...) (select ... from dual) union all (select ... from dual)

<insert id="insertListBatch" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT INTO T_APPLAUD
        (
            ID,
            name,
            age,
            sex,
            CREATE_TIME
        )
        <foreach item="item" index="index" collection="list" separator="union all">
        (
            SELECT 
                #{item.id},
                #{item.name},
                #{item.age},
                #{item.sex},
                #{item.createdTime} 
            FROM DUAL
        )
        </foreach>
    </insert>

mysq如下:

<insert id="insertListBatch" >
    insert into student ( id,name,age,sex,createdTime )
  values
    <foreach collection="list" item="item" index="index" separator=",">
      (
null,#{item.name},#{item.age},#{item.sex},#{item.createdTime}
    </foreach> 
</insert>
