根据您提供的查询代码，有几个问题需要解决：

1. `LIMIT` 和 `ORDER BY` 语句的顺序错误。在 `ORDER BY` 之前应该是 `WHERE` 语句，然后是 `GROUP BY`，最后是 `ORDER BY` 和 `LIMIT`。请将这两个语句调整到正确的位置。

2. `LEFT JOIN` 和 `JOIN` 语句之间缺少逗号。请在第一个 `LEFT JOIN` 语句和第二个 `LEFT JOIN` 语句之间添加逗号。

修改后的代码如下：

SELECT orders.id, orders.user_id, orders.cityarea_id, orders.batchcode, orders.status, 
orders.pay_status, orders.real_pay, orders.total, orders.money, orders.pay_type, 
orders.premium, orders.createtime, orders.paytime, orders.confirmtime, 
orders.is_evaluate, orders.pay_method, orders.exp_user_id, orders.return_score,
orders.is_change, orders.reward_money, orders.isvalid, orders.after_sale_status, orders.remark,
orders.use_coupon_detail, orders.block_chain_price, users.name, users.weixin_name, users.weixin_fromuser,
users.phone, wcoe.diy_area_name , writes.ActivityStatus, writes.NewMoney, records.Commission, records.ReturnRadio
FROM wsy_o2o.weixin_cityarea_orders orders 
LEFT JOIN wsy_o2o.weixin_cityarea_supply supply ON orders.cityarea_id = supply.id 
LEFT JOIN wsy_o2o.weixin_cityarea_payonline_orders wcco ON orders.batchcode = wcco.batchcode 
LEFT JOIN wsy_user.weixin_users users ON users.id = orders.user_id 
LEFT JOIN wsy_o2o.weixin_cityarea_orders_extend wcoe ON orders.batchcode = wcoe.batchcode
LEFT JOIN wsy_dream.ShopWrite writes ON orders.batchcode = writes.Batchcode 
LEFT JOIN wsy_o2o.weixin_cityarea_supply_commissons_record records ON orders.cityarea_id = records.SupplyId AND records.CreateTime < orders.createtime 
WHERE orders.types = 3 AND orders.customer_id = 41 AND orders.isvalid = true 
GROUP BY orders.batchcode 
ORDER BY records.CreateTime DESC 
LIMIT 1 OFFSET 0;

请注意，上述修改的代码仅修复了语法错误。如果仍然存在问题，可能需要进一步检查表和列名的正确性以及其他约束条件。
