Sql 对象或列名丢失或为空

我得到以下错误

对象或列名丢失或为空。对于SELECT INTO语句，请验证每个列都有名称。对于其他语句，请查找空别名。不允许定义为或[]的别名。添加名称或单个空格作为别名

对于下面显示的查询：

您能帮忙吗？

这里一行有两个逗号

 @last_mod_user_id =last_mod_user_id ,
                  ,@i=@i+1

也可能与错误消息无关，但您有一行

         Where @sup_id = supplier_id

但是，如果不知道查询中引用的所有表和视图的结构，则无法判断声明的变量@supplier_id

。查看所有这些，看看查询中是否缺少任何列引用。+1仅用于identitynt，1,1我以前从未见过。
