“on子句”中的未知列是否有JOIN错误？

标签： php mysql join

我在这里有这样的查询，我从我们的售票数据库中提取事件的数据......如果我删除这些行，它会很有效：

**IF (wp_sshow_verifys.verifyID IS NULL,TRUE,FALSE) wp_sshow_verifys**
FROM wp_sshow_sales, wp_sshow_tickets
**INNER JOIN wp_sshow_verifys ON wp_sshow_verifys.saleID=wp_sshow_sales.saleID**

这里的目标是从所有较低的live15表中提取所有数据，并且如果wp_sshow_verifys.saleID表中存在wp_sshow_sales.saleID，则仅从wp_sshow_sales + wp_sshow_tickets中提取数据。

我收到此错误：＃1054 - 'on clause'中的未知列'wp_sshow_sales.saleID'

我已经尝试了几乎所有我能想到的东西，并且看了一遍并没有让我感到困惑的答案，但在这里我正在寻求帮助。我在调用两个表时有什么问题吗？

wp_sshow_sales.saleLastName as last,

让计数列： 首先选择：第一个，最后一个，电子邮件，街道，城市，州，邮编，priceID，数量，验证 第二个选择：第一个，最后一个，电子邮件，街道，城市，州，邮编，priceID，数量

我的......我有一个名为verify的新专栏，它很难看，我不想要它。

不要混合连接符号。 摆脱where子句并用内连接替换，并将where移动到on子句

...

此外，您的最后一列与一个表共享一个名称，其名称与Abhik Chakraborty评论不同。

只是一个评论，你真的没有一个将priceID转换为值的表吗？如果数据存在于这样的表中，那么拥有外连接会简单得多。随着新的priceID进入，你必须修改这个查询...从长远来看我会想到糟糕的设计。

--------------解决遇到的新错误---

支持if语句现在添加到第一个查询10列...

您需要在第二个查询中添加一列。

至少你可以......所以列数相匹配，但也许你需要做一个类似的if语句来获得第二个查询中的结果。
