$query = $this->createQuery();
return $query->matching($query->like('linker', "$linkerKey=$linkerValue"))
->setOrderings(array('crdate' => $ordering))
->execute();
How can i debug such a generated query in extbase? When creating the same query again (but without the execute() ) and trying to display it with var_dump or the internal t3lib_div::debug i just receive a blank page.
回答1:
$query = $this->createQuery();
$result = $query->matching($query->like('linker', "$linkerKey=$linkerValue"))
->setOrderings(array('crdate' => $ordering))
->execute();
$GLOBALS['TYPO3_DB']->debugOutput = true;
return $result;
回答2:
In version 8.7 LTS, another way needs to be taken:
$queryParser = $this->objectManager->get(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getSQL());
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getParameters());
回答3:
This information is outdated and deprecated in TYPO3 8.7. Refer to @pgampe 's answer below for a more current way to debug extbase queries.
Extbase now has a QueryParser for that. In your repository method, right before returning the executed query, insert:
$parser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbQueryParser');
$queryParts = $parser->parseQuery($query);
\TYPO3\CMS\Core\Utility\DebugUtility::debug($queryParts, 'query');
The result is a table view of the query parts, split by SQL keywords, e.g.:
Keep in mind that the QueryResult that your Repository returns may still be different from the SQL query result. Extbase uses the PropertyMapper to try to convert every result row into an ExtbaseObject. If the PropertyMapper is misconfigured or the row contains data that cannot be converted to the data types according to the configuration, these Objects will silently be skipped.

This hack to extbase is dirty, but useful:
In typo3/sysext/extbase/Classes/Persistence/Storage/Typo3DbBackend.php edit the method buildQuery(array $sql) before the return statement, add:
t3lib_div::debug($statement, 'SQL Query Extbase');
Remove after use, and don't forget this will affect everything that runs on extbase, so use in dev environment only

This works as long as $GLOBALS['TYPO3_DB'] is supported. It will show you the complete build SQL query.
/**
* @param \TYPO3\CMS\Extbase\Persistence\QueryResultInterface $queryResult
* @param bool $explainOutput
* @return void
*/
public function debugQuery(
\TYPO3\CMS\Extbase\Persistence\QueryResultInterface $queryResult,
$explainOutput = false
) {
$GLOBALS['TYPO3_DB']->debugOuput = 2;
if ($explainOutput) {
$GLOBALS['TYPO3_DB']->explainOutput = true;
}
$GLOBALS['TYPO3_DB']->store_lastBuiltQuery = true;
$queryResult->toArray();
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump(
$GLOBALS['TYPO3_DB']->debug_lastBuiltQuery
);
$GLOBALS['TYPO3_DB']->store_lastBuiltQuery = false;
$GLOBALS['TYPO3_DB']->explainOutput = false;
$GLOBALS['TYPO3_DB']->debugOuput = false;
}
So with that function you can do something like this in your controller:
$all = $this->repository->findAll();
$this->repository->debugQuery($all);
回答6:
An easy way without changing any Typo3 core code and not mentioned in any forum so far is using the php "serialize()" method:
$result = $query->execute();
echo (serialize($result));
In the result object you find the SQL query (look for "statement;" ...)
回答7:
In v6.2x or later, you can debug result object in extBase like:
In repository:
return $query->execute(true); // "true" will return array result
Or also you can debug result object in Controller:
$resultObject = $this->yourRepository->findAll();
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($resultObject);

Here I post a method you can enter for debugging in any class, making a trait of it would be surely possible too. Authorship and source is mentioned in the comment, Usage too:
