Sql 获取定义不明确的列时出错

当我尝试运行以下查询时，发现列定义模糊错误：

查询在填充临时表的过程中。请提供建议。 我越来越

定义模糊的列

---

如果在任何子句中使用不带别名的JOIN和column，则会发生此错误

请重新检查查询。 我怀疑：

WHERE orm.msg_id BETWEEN `in_start_batch_id` AND `in_end_batch_id`
      AND orm.msg_id  NOT IN (SELECT msg_id FROM GTT_ERROR_RCV_LOG)
      AND orm.PROCESSING_STATUS != 'E'
    ORDER BY `msg_id`

没有数据模型，这个问题更难解决。

有一个问题

ORDER BY msg_id

---

msg_id是我可以看到的几个表上的一个字段。它不知道使用哪一个。

卸下一小部分，再试一次。错误消失了吗？如果没有，请删除一些其他内容。在ORDER BY msg_id中，您应该使用别名作为msg_id，可能是orm.msg_id可能是查询顺序的最后一部分BY msg_id？我非常确定，如果你使用编辑器，他们会给你错误的行号。首先，你从两个表中获得实验室订单OCC测试ID。你需要调试这个，转储代码并要求我们比你能更彻底地阅读它是不合适的。这不是一个真正的问题-答案是“你有一个重复的列名或别名…”请阅读。
