How Can I See the Actual SQL Queries Generated by Doctrine?

Examining Actual SQL Queries in Doctrine

When working with Doctrine, an ORM for PHP, it's common to construct queries using expressions such as:

<code class="php">$q = Doctrine_Query::create()
    ->select('id')
    ->from('MyTable');</code>
Copy after login

However, adding conditions can make it difficult to visualize the full SQL query being sent to the database. Attempting to retrieve the query using $q->getSQLQuery() will only display the prepared statement, complete with placeholder '?' characters.

To address this, it's important to understand that Doctrine utilizes prepared statements, which involve:

  1. Sending the query for preparation (returned by $q->getSQL())
  2. Sending the parameters (returned by $q->getParameters())
  3. Executing the prepared statement

Due to this mechanism, Doctrine does not maintain an actual "real" SQL query on the PHP side. Consequently, it cannot provide a full SQL representation for examination purposes.
