Mysql PhpMyAdmin不会在查询结果的底部显示查询结果操作

我可以看到查询结果操作，该操作为某些查询提供了导出查询结果的方法，但对于存在一组连接的查询的其他查询则没有。我觉得这是一种质疑。这是原因还是结果的数量

实际查询的快照：出于安全原因替换了变量

其中一个原因可能是返回了太多字段，从而禁用了底部的导出选项。

这是因为，您的查询非常长，而phpMyAdmin 4.0.3版仍在编写和使用中，在发送长查询（包括任何注释）时可能存在此“错误”。它不会显示导出选项-查询结果操作

示例：添加任何很长的注释（或命令），它将停止工作，删除它，选项将再次显示在那里

为什么有那么多

？也许是时候优化您的数据库布局或查询了。如果您没有收到任何错误，则可能是您的查询将返回大量结果，因为您有太多的联接
