使用SQL語句查詢資料後並匯出資料表，結果訂單號顯示 3E+15

原sql：

SELECT
  o.order_sn AS '訂單單號',
  o.order_amount AS '訂單支付金額',
  o.shipping_fee AS '郵費',
  o.buyer_id AS '購買人ID',
    bm.member_mobile as '購買人手機號',
    o.order_state as '訂單狀態',
  bm.member_level as '會員等級',
  a.true_name AS '收貨人',
  a.mob_phone AS '收貨人手機號',
  o.store_name AS '店鋪名稱',
  DATE_FORMAT( FROM_UNIXTIME( o.add_time ), '%m月%d日%H:%i:%s' ) AS '訂單生成時間',
  DATE_FORMAT( FROM_UNIXTIME( o.payment_time ), '%m月%d日%H:%i:%s' ) AS '訂單支付時間',
  a.area_info AS '地區',
  a.address AS '地址',
  c.reciver_info as '客服修改的地址',
  m.manufacturer_name AS '廠家',
    o.trade_no,
  g.goods_name AS '商品規格',
    d.goods_spec as '屬性',
  g.goods_num AS '商品數量',
  g.goods_price AS '商品價格',
  g.goods_pay_price AS '商品實際支付價格' ,
    c.order_message as '訂單留言',
  c.deliver_explain as '發貨備註',
    o.gift_type as '禮包等級',
    i.consignee_name as '真實姓名',
    i.audit_code as '身份證',
  d.goods_serial as '商家編碼',
    g.gid,
    d.goods_jingle as '簡介'
FROM
  bbc_order AS o
  LEFT JOIN bbc_order_goods AS g ON o.order_id = g.order_id
  LEFT JOIN bbc_order_common AS c ON c.order_id = o.order_id
  LEFT JOIN bbc_address AS a ON c.address_id = a.address_id
  LEFT JOIN bbc_goods AS d ON g.gid = d.gid
  LEFT JOIN bbc_manufacturer AS m ON m.id = g.manufacturer_id
  LEFT JOIN bbc_member as bm on o.buyer_id = bm.member_id
left join bbc_order_import_consignee i on o.order_id = i.order_id
WHERE
  o.order_state in ("20") 
 and lock_state = 0;

　　這種情況使用：CONCAT 函式將訂單號輸出為字串格式就可以了

修改後:

SELECT
CONCAT(o.order_sn,'') AS '訂單單號',
o.order_amount AS '訂單支付金額',
