使用MySQL和PHP进行查询时出错

我在使用MySQL的查询中遇到以下错误

错误：#1064-您的SQL语法有错误；检查与MySQL服务器版本对应的手册，以了解正确的语法 使用near'pr.pro_Id=p.pro_Id作为s加入db_供应商 pr.supplier\u id=s.supplier\u id在第1行加入db\u或'

我在下面解释我的问题

 SELECT
 pr.pro_data_id,pr.pro_Id,pr.specification,pr.Discount,pr.Offer,pr.unit_cost_price,pr.unit_sale_price,pr.quantity
 AS
 total_quantity,pr.shipping_charge,pr.product_code,pr.policy,pr.supplier_id,pr.latest_sale_price,pr.pro_status,pr.sale_price,p.Product_name,s.user_name,op.order_id,op.quantity
 AS
 ordered_quantity,op.final_price,op.prod_tot_price,op.delstatus,op.status,o.order_date,o.shipping_id,sh.name
 FROM db_product_data AS pr JOIN db_product_info AS p
 pr.pro_Id=p.pro_Id JOIN db_supplier AS s pr.supplier_id=s.supplier_id
 JOIN db_order_products AS op pr.pro_data_id=op.pro_data_id JOIN
 db_order AS o op.order_id=o.order_id JOIN  db_shipping_address AS sh
 o.shipping_id=sh.shipping_id WHERE pr.pro_data_id='63' AND
 pr.pro_Id='36' ORDER BY pr.pro_data_id DESC

如何解决此错误？

上缺少

JOIN db_product_info AS p ON pr.pro_Id=p.pro_Id

上缺少
，
-

JOIN db_product_info AS p ON pr.pro_Id=p.pro_Id

查询的所有联接中都缺少
ON
运算符
