title: Unknown database type geometry requested error in doctirne:mapping:import for Symfony2
body: <p>I'm getting the following error while running the doctrine:mapping:import command in Symfony2. I'm using SQL Server 2012 even though the error says " 2008Platform may not support it".</p>
  
  <pre><code>  [Doctrine\DBAL\DBALException]                                                
    Unknown database type geometry requested, Doctrine\DBAL\Platforms\SQLServer  
    2008Platform may not support it. 
  </code></pre>
  
  <p>My database configuration look like this:</p>
  
  <pre><code>doctrine:
  dbal:
      driver:   pdo_sqlsrv
      host:     localhost
      port:     1433
      dbname:   test
      user:     user
      password: password
      charset:  UTF8
  </code></pre>
  
  <p>I have also tried setting the mapping type to string. But it gives the same error.</p>
  
  <p>When I try the command using MyMainBundle string --force. I get this error:</p>
  
  <pre><code> [Doctrine\ORM\Tools\Export\ExportException]          
    The specified export driver 'string' does not exist
  </code></pre>
  
  <p>I have used the driver <a href="http://www.microsoft.com/en-us/download/details.aspx?id=20098" rel="nofollow">here</a> for php.</p>
