mybatis针对Oracle数据库进行（单个或多个条件）批量操作（新增、修改、删除）的sql写法
1、批量新增:
2、批量修改：
单个条件、单个修改字段：
多个条件、多个修改字段：
3、批量删除：
单个条件：
多个条件：
多个条件第2种形式：
4、批量查询：（未验证）
<insert id="addMonthDutyIntoDB" parameterType="java.util.List">
insert into TB_DUTY select SEQ_TB_DUTY.nextval,A.* from(
<foreach collection="list" item="item" index="index" separator="union">
SELECT #{item.dscd}, #{item.unitId},#{item.year},#{item.month},#{item.day},#{item.weekDay},
#{item.morningPeopleIds}, #{item.morningPeopleNames},#{item.afternoonPeopleIds},#{item.afternoonPeopleNames},#{item.eveningPeopleIds},
#{item.eveningPeopleNames},#{item.leaderIds},#{item.leaderNames},#{item.flag},#{item.remark},#{item.day0} FROM DUAL
</foreach>
) A
</insert>
2、批量修改：
单个条件、单个修改字段：
<update id="auditMultiByIds" parameterType="java.util.List">
update tb_code_name_result_new set state=#{state,jdbcType=INTEGER} where id in
<foreach collection="list" item="item" index="index" open="(" separator="," close=")" >
#{item}
</foreach>
</update>
多个条件、多个修改字段：
<update id="updateByMultiConditions" parameterType="java.util.List">
<foreach collection="list" item="item" index="index" open="begin" close="; end;" separator=";">
update TB_DUTY
<set>
<if test="item.morningPeopleIds != null and item.morningPeopleIds != '' " >
MORNING_PEOPLE_IDS=#{item.morningPeopleIds,jdbcType=VARCHAR},
</if>
<if test="item.morningPeopleNames != null and item.morningPeopleNames != '' " >
MORNING_PEOPLE_NAMES=#{item.morningPeopleNames,jdbcType=VARCHAR},
</if>
<if test="item.afternoonPeopleIds != null and item.afternoonPeopleIds != '' " >
AFTERNOON_PEOPLE_IDS=#{item.afternoonPeopleIds,jdbcType=VARCHAR},
</if>
<if test="item.afternoonPeopleNames != null and item.afternoonPeopleNames != '' " >
AFTERNOON_PEOPLE_NAMES=#{item.afternoonPeopleNames,jdbcType=VARCHAR},
</if>
<if test="item.eveningPeopleIds != null and item.eveningPeopleIds != '' " >
EVENING_PEOPLE_IDS=#{item.eveningPeopleIds,jdbcType=VARCHAR},
</if>
<if test="item.eveningPeopleNames != null and item.eveningPeopleNames != '' " >
EVENING_PEOPLE_NAMES=#{item.eveningPeopleNames,jdbcType=VARCHAR},
</if>
<if test="item.leaderIds != null and item.leaderIds != '' " >
LEADER_IDS=#{item.leaderIds,jdbcType=VARCHAR},
</if>
<if test="item.leaderNames != null and item.leaderNames != '' " >
LEADER_NAMES=#{item.leaderNames,jdbcType=VARCHAR},
</if>
</set>
where DUTY_ID=#{item.dutyId,jdbcType=INTEGER}
</foreach>
</update>
3、批量删除：
单个条件：
<delete id="delMultiByIds" parameterType="java.util.List">
delete from TB_CODE_NAME_RESULT_NEW
where ID in
<foreach collection="list" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</delete>
多个条件：
<delete id="delMultiByIds2" parameterType="java.util.List">
delete from tb_duty A
where exists
(
select 1 from(
<foreach collection="list" item="item" index="index" separator="union all">
select B.* from tb_duty B where 1=1 and B.dscd=${item.dscd} and B.unit_id=${item.unitId} and
B.year=${item.year} and B.month=${item.month} and B.flag=${item.flag}
</foreach>
)S where A.duty_id=S.duty_id
)
</delete>
多个条件第2种形式：
<!-- 成功删除返回的是-1而不是删除的记录数 -->
<delete id="delMultiByIds" >
<foreach collection="list" item="item" index="index" open="begin" close="; end;" separator=";">
delete from tb_duty_statistics a
where a.person_id
in(
select b.person_id from tb_duty_person_info b where b.dscd=#{dscd,jdbcType=CHAR} and b.unit_id=#{unitId,jdbcType=INTEGER}
)
and substr(a.duty_id,1,7)=#{item.dutyId,jdbcType=CHAR}
</foreach>
</delete>
4、批量查询：（未验证）
<select id="selectBySomePoiIds" resultType="list" parameterType="java.util.Map">
SELECT <include refid="Base_Column_List" /> FROM 表名
WHERE poi_id in
<foreach collection="poiIds" item="poiId" index="index" open="(" close=")" separator=",">
#{poiId}
</foreach>
AND pass_uid = #{passUid}
<if test="status != null">
AND status = #{status,jdbcType=BIGINT}
</if>
</select>
