Oracle学习笔记03：oracle批量插入语句

首先，Oracle批量插入和Mysql批量插入语句格式是不一样；

Mysql语句，如下：

    <insert id="save" parameterType="PlatformAssoRecord" keyColumn="id" keyProperty="id">
        insert into S_PLATFORM_ASSO_RECORD(
        "id",
        "asso_a_id",
        "asso_b_id",
        "type",
        "status",
        "del_flag",
        "create_user_id",
        "create_time"
        ) values (
        #{id},
        #{assoAId},
        #{assoBId},
        #{type},
        #{statu},
        #{delFlag},
        #{createUserId},
        #{createTime}
        )
    </insert>

Oracle语句，如下：

    <insert id="saveBatch" parameterType="list" >
        insert ALL
        <foreach collection="list" item="item" separator="">
            INTO
            S_PLATFORM_ASSO_RECORD(
            "id",
            "asso_a_id",
            "asso_b_id",
            "type",
            "status",
            "del_flag",
            "create_user_id",
            "create_time"
            )
            values
            (
            #{item.id, jdbcType=BIGINT},
            #{item.assoAId, jdbcType=VARCHAR},
            #{item.assoBId, jdbcType=VARCHAR},
            #{item.type, jdbcType=INTEGER},
            #{item.status, jdbcType=INTEGER},
            #{item.delFlag, jdbcType=INTEGER},
            #{item.createUserId, jdbcType=VARCHAR},
            #{item.createTime, jdbcType=TIMESTAMP}
            )
        </foreach>
        SELECT 1 FROM DUAL
    </insert>

其中 

　　insert all into并不表示一个表中插入多条记录，而是表示多表插入各一条记录，而这多表可以是同一个表，就成了单表插入多条记录。

　　SELECT 1 FROM DUAL 的作用，可以参考博客：https://www.cnblogs.com/mingmingcome/p/9310371.html
