MariaDB / hasStream fails to detect existing Stream

[Andreas Heissenberger]

The comparing fails as $statement->fetchColumn() returns a Number:

pdo-event-store/src/MariaDbEventStore.php

Lines 174 to 194 in cc4acb5

     public function hasStream(StreamName $streamName): bool 
     { 
         $sql = <<<EOT 
 SELECT COUNT(1) FROM `$this->eventStreamsTable` 
 WHERE real_stream_name = :streamName; 
 EOT; 
  
         $statement = $this->connection->prepare($sql); 
  
         try { 
             $statement->execute(['streamName' => $streamName->toString()]); 
         } catch (PDOException $exception) { 
             // ignore and check error code 
         } 
  
         if ($statement->errorCode() !== '00000') { 
             throw RuntimeException::fromStatementErrorInfo($statement->errorInfo()); 
         } 
  
         return '1' === $statement->fetchColumn(); 
     } 

Problem is fixed in MySqlEventStore.php

pdo-event-store/src/MySqlEventStore.php

Line 193 in cc4acb5

 return 1 === (int) $statement->fetchColumn();
