计算Doctrine执行的查询次数

[英]Count number of queries performed by Doctrine

原文 2010-07-17 08:43:46 2 2 php/ doctrine

I am using Doctrine and sometimes I've the feeling that it is doing much more things than what I am expecting, so I would like to have more information (and therefore more control) about what Doctrine is doing. 我正在使用Doctrine，有时我觉得它做的事情比我期望的要多得多，所以我希望得到更多关于Doctrine正在做什么的信息（因此更多的控制）。

So, how I could count the total number of queries that Doctrine is doing?. 那么，我如何计算Doctrine正在进行的查询总数？ It would be nice if I could also find the SQL statements that Doctrine is performing implicitly, (apart of the ones that I am creating). 如果我还能找到Doctrine隐式执行的SQL语句（除了我正在创建的那些语句），那将是很好的。

Thank you in advance! 先感谢您！

Find the section that's headed " Profiling with Doctrine " This is specific for the use with a framework but you should figure out how to do it without the framework, it's not hard 找到标题为“ 使用Doctrine进行概要分析 ”的部分这是特定于框架的使用，但你应该弄清楚如何在没有框架的情况下进行，这并不困难

Doctrine has a Profiler components, that allows one to keep track of every access that's done to the database. Doctrine有一个Profiler组件，允许用户跟踪对数据库所做的每次访问。

See : Profiler 请参阅： Profiler

Note, though, that the profiler could get you much more informations that you expect : depending on how you configure it, it'll indicate each time some data is fetched from the DB as an event (even if it doesn't mean a query is performed each time) . 但请注意，探查器可以为您提供更多您期望的信息：根据您的配置方式，它会指示每次从数据库中提取某些数据作为事件（即使它不代表查询每次执行） 。

Also; 也; as Doctrine is using prepared statements, you'll never be able to see any "real" SQL query : you'll only see statements, and the corresponding data. 由于Doctrine正在使用预处理语句，您将永远无法看到任何“真正的”SQL查询：您只会看到语句和相应的数据。
