前言

提示:在orcale和mybatis执行批量插入是不一样的。

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>

方式3：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>
