教义 - 如何打印真正的sql，而不仅仅是准备好的语句？ [英] Doctrine - How to print out the real sql, not just the prepared statement?

问题描述

我们正在使用Doctrine，PHP ORM。我正在创建一个这样的查询：

  $ q = Doctrine_Query :: create（） - > select（'id' - >从（ 'MyTable的'）; 
  

然后在函数中，我添加各种各样的条款和事物，如此

  $ q-> where（'normalisedname =？OR name =？'，array（$ string，$ originalString））; 
  

之后， execute（）那个查询对象，我想打印出原始SQL以便检查它，并执行以下操作：

  $ q- > getSQLQuery（）; 
  

但是，只打印出准备好的语句，而不是完整的查询。我想看看它是发送到MySQL，而是打印出一个准备好的声明，包括？。有没有办法查看完整查询？

解决方案

原则不是向数据库发送真正的SQL查询服务器：它实际上是使用准备的语句，这意味着：

• 发送语句，为准备（这是由...返回的 $ query-> getSql（））


• 然后，发送参数（由$ code $ $ query-> getParameters（））


• 并执行准备好的语句

这意味着PHP方面从来没有一个真正的SQL查询 - 所以Doctrine不能显示。

We're using Doctrine, a PHP ORM. I am creating a query like this:

$q = Doctrine_Query::create()->select('id')->from('MyTable');

and then in the function I'm adding in various where clauses and things as appropriate, like this

$q->where('normalisedname = ? OR name = ?', array($string, $originalString));

Later on, before execute()-ing that query object, I want to print out the raw SQL in order to examine it, and do this:

$q->getSQLQuery();

However that only prints out the prepared statement, not the full query. I want to see what it is sending to the MySQL, but instead it is printing out a prepared statement, including ?'s. Is there some way to see the 'full' query?

解决方案

Doctrine is not sending a "real SQL query" to the database server : it is actually using prepared statements, which means :

• Sending the statement, for it to be prepared (this is what is returned by $query->getSql())
• And, then, sending the parameters (returned by $query->getParameters())
• and executing the prepared statements

This means there is never a "real" SQL query on the PHP side — so, Doctrine cannot display it.
