TYPO3 Core

Steps to reproduce

• Create a custom query with a IN statement
• Example query on tt_content table
  

  $query->matching(
      $query->logicalAnd([
          $query->in(
              'CType', $CTypes // <- this string values does not has quotes
          ),
          $query->in(
              'pid', $pages
          )
      ])
  );
  

Possible workaround

if (TYPO3_branch === '8.7') {
    $CTypes = array_map(function($a) { return '"'.$a.'"';}, $CTypes);
}
