170829、mybatis使用oracle和mybatis中批量更新

一、mybatis 执行批量更新 batch update 的方法(mysql 数据库)

1、数据库连接必须配置:&allowMultiQueries=true(切记一定要加上这个属性,否则会有问题,切记! 切记! 切记!)
  我的配置如下:jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
2、批量修改并加判断条件(修改字段可选)
<!-- 批量更新 -->
    <update id="updateMatchs" parameterType="java.util.List">
        <foreach collection="matchs" item="item" index="index" open="" close=""separator=";">
            update t_match
            <set>
                <if test="item.title !=null">
                    TITLE = #{item.title,jdbcType=VARCHAR},
                </if>
                <if test="item.homeScore !=null">
                    HOME_SCORE = #{item.homeScore,jdbcType=INTEGER},
                </if>
                <if test="item.visitScore !=null">
                    VISTT_SCORE = #{item.visitScore,jdbcType=INTEGER},
                </if>
                <if test="item.liveSource !=null">
                    LIVE_SOURCE = #{item.liveSource,jdbcType=VARCHAR},
                </if>
                <if test="item.liveURL !=null">
                    LIVE_URL = #{item.liveURL,jdbcType=VARCHAR},
                </if>
                <if test="item.isHotMatch !=null">
                    IS_HOT_MATCH = #{item.isHotMatch,jdbcType=VARCHAR}
                </if>
            </set>
        where HOME_TEAM_ID = #{item.homeTeamId,jdbcType=VARCHAR} and
        VISIT_TEAM_ID = #{item.visitTeamId,jdbcType=VARCHAR} and
        MATCH_TIME = #{item.matchTime,jdbcType=BIGINT}
        </foreach>
    </update>
3、java 接口
  /**
     * 批量修改赛程
     * 
     * @param matchs
     * @throws DaoException
     */
    void updateMatchs(@Param(value = "matchs")List<MatchBasic> matchs);

二、mybatis 执行批量更新 batch update 的方法(oracle 数据库)

1、批量修改并加判断条件(修改字段可选)

<update id="batchUpdateSplitSinglePickCurrency" parameterType="java.util.List">
        <foreach collection="list" item="item" index="index" open="begin" close=";end;" separator=";">
            UPDATE ZC_TR_MULTI_ORDER_CURRENCY
            <set>
                <if test="item.sysCorderCode != null">
                    SYS_CORDER_CODE = #{item.sysCorderCode,jdbcType=VARCHAR},
                </if>
            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.sysPorderCode != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                SYS_PORDER_CODE </span>= #{item.sysPorderCode,jdbcType=<span style="color: rgba(0, 0, 0, 1)">VARCHAR},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;

            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.bizPorderCode != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                BIZ_PORDER_CODE </span>= #{item.bizPorderCode,jdbcType=<span style="color: rgba(0, 0, 0, 1)">VARCHAR},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;

            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.originalOrderCode != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                ORIGINAL_ORDER_CODE </span>= #{item.originalOrderCode,jdbcType=<span style="color: rgba(0, 0, 0, 1)">VARCHAR},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;

            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.splitUserId != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                SPLIT_USER_ID </span>= #{item.splitUserId,jdbcType=<span style="color: rgba(0, 0, 0, 1)">VARCHAR},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;

            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.createDate != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                CREATE_DATE </span>=<span style="color: rgba(0, 0, 0, 1)"> #{item.createDate},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;

            &lt;<span style="color: rgba(0, 0, 255, 1)">if</span> test="item.updateDate != null"&gt;<span style="color: rgba(0, 0, 0, 1)">
                UPDATE_DATE </span>=<span style="color: rgba(0, 0, 0, 1)"> #{item.updateDate},
            </span>&lt;/<span style="color: rgba(0, 0, 255, 1)">if</span>&gt;
        &lt;/set&gt;<span style="color: rgba(0, 0, 0, 1)">
        where id </span>= #{item.id,jdbcType=<span style="color: rgba(0, 0, 0, 1)">VARCHAR}
    </span>&lt;/foreach&gt;
&lt;/update&gt;</pre>

2、java 接口

  /**
* @Desc : 批量更新大批量子订单详情信息 * @Author : ZRP * @Date : 2018/1/26 15:24 */ int batchUpdateSplitSinglePickCurrency(@Param(value = "list") List<MultiOrderCurrency> list) throws Exception;
