TYPO3 Core

Hi,

I used today the method '\TYPO3\CMS\Extbase\Persistence\Generic\Query::statement()' my first time. I didn't have troubles with another methods of the queries of Extbase. But I will try to explain my enviroment.

I have to use this statement, because I need to user the REGEXP in some queries. I tried first:

$query->statement(
    "SELECT * FROM tx_myext_mytable WHERE schluessel != ? AND schluessel REGEXP ?", 
    array($key, '[1-9]{3}' . substr($key, 3, 5) . '.*')
);

,but it returns an error like this:

Uncaught TYPO3 Exception
#1247602160: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '? AND schluessel REGEXP ?' at line 1

So, I tried to make it in another way:

 $sql = "SELECT * FROM tx_myext_mytable " 
                    . "WHERE schluessel != ? AND schluessel REGEXP ?";

$query->statement(
    $this->objectManager->get(\TYPO3\CMS\Core\Database\PreparedStatement::class, $sql, 'tx_stala_domain_model_gebiet'), 
    array($key, '[1-9]{3}' . substr($key, 3, 5) . '.*')
);        

now it works but not at all. Also, 'tx_myext_mytable' contents 3060 elements, the result with specifics parameter for this query ($key) returns the corrects elements in an object of type '\TYPO3\CMS\Extbase\Persistence\Generic\Query\QueryResult', but the size of the object is wrong, a few examples of the output from the Extbase Debugger

Do i make something wrong? Or Is it a bug of the system?

Thank you
