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 tried this:
$query = $this->createQuery();
$query->statement('SELECT * FROM `my_table`
WHERE field = ? ORDER BY date DESC LIMIT 1',
array($condition));
$results = $query->execute();
and this:
$query = $this->createQuery();
$query->matching($query->equals('field', $condition));
$query->setOrderings(array('date' => Tx_Extbase_Persistence_QueryInterface::ORDER_DESCENDING));
$query->setLimit(1);
$results = $query->execute();
both returns null as result.
Is it possible to get the sql that the class creates to look where the bug is?
I've looked in some extbase persistent classes but didn't find a clue
EDIT: For those who are interested.. i found a "solution".
If you create the query with the statement() method, you can print the query with this function
echo $query->getStatement()->getStatement();
It doesn't replace the placeholder. But you can get the Variables with this method
var_dump($query->getStatement()->getBoundVariables());
Thats the best Solution that i found, without editing the extbase extenstions

In TYPO3 6.2 you can use Extbase DebuggerUtility to debug the query.
Add this code before $query->execute():
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbQueryParser');
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->parseQuery($query));
For TYPO3 8.7+ use this code instead:
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtilityGeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
$doctrineQueryBuilder = $queryParser->convertQueryToDoctrineQueryBuilder($query);
$doctrineQueryBuilderSQL = $doctrineQueryBuilder->getSQL();
$doctrineQueryBuilderParameters = $doctrineQueryBuilder->getParameters();

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/sysext/extbase/Classes/Persistence/Storage/Typo3DbBackend.php
typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php
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

$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

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.

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 ("statement;" ...)

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.

I just extended the above snippet, with a $_GET condition. for debugging, just append "?dbg_table=tx_some_of_my_tables" to your address, and you're ready to go ;-)
if (in_array($_GET['dbg_table'], $sql['tables'])) {
echo('<div style="background: #ebebeb; border: 1px solid #999; margin-bottom: 20px; padding: 10px;"><pre style="white-space: normal">'.$statement.'</pre></div>');
}

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().
