It seems because removing deprecation "replacePlaceholders" since 6.2 in this classes the placeholder doesnt replace the boundVariables:


In Statement.php the constructor wants a type of \TYPO3\CMS\Core\Database\PreparedStatement but type of TYPO3\CMS\Extbase\Persistence\Generic\Qom\Statement from repository is given, see in screen.

So there a 2 ways to workaround this fault:

1. Outsource, fork and modify from Typo3DbBackend.php
the "replacePlaceholders" method in a helper class or a private function in your repository like this:

    private function replacePlaceholders(&$sqlString, array $parameters, $tableName = 'foo')
        if (substr_count($sqlString, '?') !== count($parameters)) {
            throw new \TYPO3\CMS\Extbase\Persistence\Generic\Exception('The number of question marks to replace must be equal to the number of parameters.', 1242816074);
        $offset = 0;
        foreach ($parameters as $parameter) {
            $markPosition = strpos($sqlString, '?', $offset);
            if ($markPosition !== FALSE) {
                if ($parameter === NULL) {
                    $parameter = 'NULL';
                } elseif (is_array($parameter) || $parameter instanceof \ArrayAccess || $parameter instanceof \Traversable) {
                    $items = array();
                    foreach ($parameter as $item) {
                        $items[] = $GLOBALS['TYPO3_DB']->fullQuoteStr($item, $tableName);
                    $parameter = '('.implode(',', $items).')';
                } else {
                    $parameter = $GLOBALS['TYPO3_DB']->fullQuoteStr($parameter, $tableName);
                $sqlString = substr($sqlString, 0, $markPosition).$parameter.substr($sqlString, ($markPosition + 1));
            $offset = $markPosition + strlen($parameter);

Use it to replace der boundVariables and use

$this->replacePlaceholders($sql, $constraints, 'tx_myext_domain_model_mymodel');

with replaced statement in repository.

2. Use Oldshool $GLOBALS['TYPO3_DB']->sql_query

  • Target version changed from 7.2 (Frontend) to 7.4 (Backend)

Updated by Mathias Bruckmoser over 6 years ago

Why change target to 7.4? This is a central important funktion, that many extensions will break.

Updated by Mathias Brodala about 6 years ago

How about directly using PreparedStatement here instead?

we've reworked this part now with proper DBAL and native prepared statements. So this issue is finally solved with TYPO3 v8, right?

  • Status changed from Needs Feedback to Closed

No feedback since the last 90 days => closing this issue. Moreover, version 7.6 has reached its end of life on December 2018 and now support is only available via ELTS (see https://typo3.com/products/extended-support)

If you think that this is the wrong decision or experience the issue again on recent TYPO3 versions like 8.7.x or 9.5.x and have more information about how to reproduce your problem, please reopen it or open a new issue with a reference to this one.

Thank you and best regards
