Extbase - get created sql from query

Question

i want to get some database tables from my typo3 extensions. The Extension is based on extbase.

The query always returns nothing but the data exists

I\'ve tr

Answer 1

$query = $this->createQuery();
$query->getQuerySettings()->setReturnRawQueryResult(TRUE);
$getHotelInfo = 'SELECT * FROM `my_table` WHERE field = ? ORDER BY date DESC LIMIT 1';
return $query->statement($getHotelInfo)->execute();

For executing query you have to write 'setReturnQueryResult' on your repository

Answer 2

Improvement to biesiors answer:

As Extbase replaces some placeholders after calling buildQuery(), you might prefer to place the debug output into getObjectDataByQuery(), just after $this->replacePlaceholders($sql, $parameters, $tableName);

if (strpos($sql, "your_table_name.")) {
    debug($sql, 'my debug output');
};

Also, better use debug() instead of var_dump().

Answer 3

A cleaner way to debug your statements when using TYPO3 6.1 is to use the query parser of Typo3DbBackend.

$parser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbBackend');
$params = array();
$queryParts = $parser->parseQuery($query, $params);

\TYPO3\CMS\Core\Utility\GeneralUtility::devLog('query', 'my_extension', 1, array('query' => $queryParts, 'params' => $params));

The parser returns an array containing the different parts of the generated SQL statement.

With TYPO3 6.2 the parseQuery method was moved to Typo3DbQueryParser and lost its second parameter.

Answer 4

Check this snippet, although it's not very comfortable in use it helps a lot:

in general you need this code at the end of the buildQuery(array $sql) method (*) - right before return $statement;

if (in_array("your_table_name", $sql['tables'])) {
    var_dump($statement);
    print_r($statement);
}

(*) Class file:

• TYPO3 ver.: 4.x: typo3/sysext/extbase/Classes/Persistence/Storage/Typo3DbBackend.php
• TYPO3 ver.: 6.x: typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php

In 6.2.x ...

You can try within \TYPO3\CMS\Core\Database\DatabaseConnection::exec_SELECTquery method, just add the condition after fetching the $query, like (trim is important!):

public function exec_SELECTquery($select_fields, $from_table, $where_clause, $groupBy = '', $orderBy = '', $limit = '') {
    $query = $this->SELECTquery($select_fields, $from_table, $where_clause, $groupBy, $orderBy, $limit);

    if (trim($from_table) == 'fe_users') {
        DebuggerUtility::var_dump($query);
    }

// rest of method

Answer 5

i suggest set this in typo3conf/LocalConfiguration.php file under 'SYS' array

'SYS' => array(
......
'displayErrors' => 1,
'sqlDebug' => 1
.......
)

and then write wrong field name in query intentionally and then execute code. this will show last query execute with error.

Answer 6

In TYPO3 6.2 you can use Extbase DebuggerUtility to debug the query.

Add this code before $query->execute():

/** @var Typo3DbQueryParser $queryParser */
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbQueryParser');
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->parseQuery($query));
