Hallo Tom.

Welchen "alten Methoden" hast Du versucht?

Ein Weg (der zugegeben nicht der eleganteste ist) sollte weiterhin sein, bewusst einen SQL-Fehler einzubauen. Dann sollte in der Fehlermeldung die (fehlerhafte) Query stehen.

Viele Grüße
Julian

Hiermit erhältst du das prepared Statement:
$queryParser = $this->objectManager->get(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getSQL());

Dort wirst du einige Platzhalter sehen die mit ":dcValue" beginnen.
Die Werte die bei der eigentlichen Ausführung benutzt werden kriegst du hiermit:
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getParameters());

Danke für den super Tipp mit dem QueryParser.

Das hat mich motiviert das ganze noch weiter zu treiben und das ganze in eine hübsche Methode zu verpacken die auch gleich die Werte ins PreparedStatement übernimmt und das SQL formattiert ausgibt. Vielleicht brauchts ja wer :)

'</code>'; } else { echo $statement; } if ($exit) { exit; }
}

Und dann aufrufen mit

$this->debugQuery($query);
