先上程式碼：

 <insert id="copyinsertBatch" parameterType="java.util.List" useGeneratedKeys="false" >
	begin 
	insert into CEB_DEPARTURE_HEAD_HIS
	<foreach item="item" collection="dataList" separator=" UNION ALL " index="index" >
	   <if test="index != 0">
			<choose>
				<when test="index % 1000 ==999">; insert into CEB_DEPARTURE_HEAD_HIS </when>
			</choose>
		</if>
		 select * from CEB_DEPARTURE_HEAD where ID = #{item}  
	</foreach>;
	
	
	insert into CEB_DEPARTURE_LIST_HIS
	<foreach item="item" collection="dataList" separator=" UNION ALL " index="index" >
		<if test="index != 0">
			<choose>
				<when test="index % 1000 ==999">; insert into CEB_DEPARTURE_LIST_HIS </when>
			</choose>
		</if>
		 select * from CEB_DEPARTURE_LIST where ID = #{item}  
	</foreach>; 
	end;
</insert>
 

重點：必須用 begin  end;  把多條sql語句 拼再一起，每個sql 用分號“；”隔開；

begin 

   sql1;

   sql2;

end;

弊端：沒有返回執行量
