Mysql 错误代码：1054未知列'；try.tb#u stores.division'；在'；关于第'条；

早安，我试图运行此查询，但遇到了一个错误，即使该列确实存在于tb_分区中

有人能帮我解决这个错误吗：

on子句中的未知列“try.tb_stores.division”

您只是在使用table department和client，而不是tb_stores，这就是您出现此错误的原因：

---

要么是

公司

列不存在，要么是

公司代码

列不存在，要么两者都不存在。您的查询在

加入

操作的任何部分都不使用

tb分区

。你能发布你收到的确切错误消息吗？@TimBiegeleisen对不起，我忘了输入错误。错误是“on子句”中的未知列“try.tb_stores.division”。@GiorgosBetsos即使我在tb_divisions中使用join，错误仍然是相同的。在这种情况下，您能否发布生成此错误的实际查询？
