本文介绍使用MyBatis进行数据库批量插入和更新的具体实现方法。通过XML配置文件展示了如何利用foreach和trim标签实现对多条记录的同时处理，特别针对插入和更新操作进行了详细说明。

批量插入案例:

<insert id="insertList">
insert into t_area_open
<trim prefix="(" suffix=")" suffixOverrides="," >
`rowid`,
fid,
fprovince_name,
fprovince_code,
fcity_name,
fcity_code,
fstatus,
fcreatetime,
fupdatetime,
foperator,
</trim>
values
<foreach collection="list" item="item" separator=",">
<trim prefix=" (" suffix=")" suffixOverrides="," >
#{ item.rowid,jdbcType=INTEGER },
#{ item.fid,jdbcType=VARCHAR },
#{ item.fprovinceName,jdbcType=VARCHAR },
#{ item.fprovinceCode,jdbcType=TINYINT },
#{ item.fcityName,jdbcType=VARCHAR },
#{ item.fcityCode,jdbcType=SMALLINT },
#{ item.fstatus,jdbcType=INTEGER },
#{ item.fcreatetime,jdbcType=TIMESTAMP },
#{ item.fupdatetime,jdbcType=TIMESTAMP },
#{ item.foperator,jdbcType=VARCHAR },
</trim>
</foreach>
</insert>

批量更新:

<update id="updateIntegral" parameterType="java.util.List">
    UPDATE t_integral
    SET
    fupdatetime =
    <foreach collection="list5" item="integral" separator=" " open="case fid" close="end">
       WHEN #{integral.id,jdbcType=VARCHAR} THEN NOW()
    </foreach>
    ,fintegral =
    <foreach collection="list5" item="integral" separator=" " open="case fid" close="end">
       WHEN #{integral.id,jdbcType=VARCHAR} THEN #{integral.integral,jdbcType=DECIMAL}
    </foreach>
        WHERE fid IN
    <foreach collection="list5" item="integral" separator="," open="(" close=")">
    #{integral.id,jdbcType=VARCHAR}
    </foreach>
    AND fkeyarea IN
    <foreach collection="list5" item="integral" separator="," open="(" close=")">
    #{integral.areaKey,jdbcType=SMALLINT}
    </foreach>
</update>
