mybatis中特殊SQL的几种配置方法

1.in条件for循环
<select id="getBooList" resultMap="java.util.Map" parameterType="java.util.List" >
select booking_no, max(booking_general_seq) max_seq from interface_booking_t where booking_no in
<foreach item="item" index="index" collection="list" open="(" separator="," close=")">
#{item}
</foreach>
group by booking_no
</select>
2.insert并且返回主键
<insert id="insertAndGetId" parameterType="com.phy.mlisp.management.domain.Document">
<selectKey resultType="long" order="BEFORE" keyProperty="id">
SELECT MLISP_DOCUMENT_SEQ.NEXTVAL as ID from DUAL
</selectKey>
insert into MLISP_DOCUMENT_T (ID, NAME, ALIAS,
FILE_SIZE,CONTENT,STATUS,CREATE_BY,CREATE_DATE,LAST_UPDATE_BY,
LAST_UPDATE_DATE)
values (#{id},#{name,jdbcType=VARCHAR}, #{alias,jdbcType=VARCHAR},#{fileSize,jdbcType=INTEGER},
#{content,jdbcType=BLOB},
#{status,jdbcType=INTEGER},#{createBy,jdbcType=VARCHAR},SYSDATE,
#{lastUpdateBy,jdbcType=VARCHAR},SYSDATE)
</insert>

3.批量insert
<insert id="batchInsert" parameterType="java.util.List">
insert into INTERFACE_BOOKING_CONTA_T (ID, BOOKING_ID, BOOKING_CONTAINER_SEQ,
CONTA_TYPE, CONTA_SIZE, CONTA_QUANTITY,
CONTA_SIZE_TYPE_ISO)
select interface_booking_conta_seq.NEXTVAL,A.* from(
<foreach collection="list" item="item" index="index" separator="UNION ALL" >
(select #{item.bookingId,jdbcType=DECIMAL}, #{item.bookingContainerSeq,jdbcType=DECIMAL},
#{item.contaType,jdbcType=VARCHAR}, #{item.contaSize,jdbcType=VARCHAR}, #{item.contaQuantity,jdbcType=DECIMAL},
#{item.contaSizeTypeIso,jdbcType=VARCHAR} from dual)
</foreach>) A
</insert>

4.批量更新
<update id="batchUpdate" parameterType="java.util.List">
<foreach collection="list" item="item" index="index" open="begin" close=";end;" separator=";">
UPDATE WCP_DISPATCH_CONTA_T
<set>
<if test="item.dispatchId != null">
DISPATCH_ID = #{item.dispatchId,jdbcType=DECIMAL},
</if>
</set>
WHERE DISPATCH_ID = #{item.dispatchId,jdbcType=DECIMAL}
</foreach>
</update>
