如果你建议一些可以回溯查询所使用的视图或模块的工具，那将会有所帮助;提供是否存在这样的事情。如果查看查询会产生共鸣，请写评论。

非常感谢..

Answer 1

我不会太担心那些只发生过一次的事情。大多数只是SELECT * FROM big_table，最有可能是通过一些管理员完成的。我不确定什么会获取整个会话表，这对我来说并不是很有用。

无论如何，多次出现的其他查询很可能是由视图生成的：

LEFT JOIN term_node term_node_value_0
  ON node.vid = term_node_value_0.vid AND term_node_value_0.tid = N

执行其中20个连接会减慢任何查询速度，这也是查看视图的原因。视图使得通用查询不知道您真正想要做什么。所以它可以做出任何假设，这就是为什么它在某些情况下可以做出像这样的疯狂查询。唯一的解决方法是自定义代码视图或仅代替查询。当事情有点复杂时，视图很难对术语进行良好的查询，因为术语具有1对多的关系（1个术语可以与节点相关联）。

因此，请查看您拥有的视图，您可以使用视图UI中的缓存处理此视图。

Answer 2

安装并启用devel模块。

导航至模块设置页面（example.com/admin/settings/devel）并检查

收集查询信息
显示查询日志

这会将页面请求的每个查询写入页面底部，并告诉您编写查询的函数（where列）。函数名称是moduleName_functionName。

googletorp完全正确。
