title: Doctrine column names case sensitivity
body: <p>I'm trying to query mssql database with Doctrine. I set up connection, built schema from database and built classes. All went smoothly, but now when I try to query database:</p>
  
  <pre><code>symfony doctrine:dql "from TABLE_NAME"
  </code></pre>
  
  <p>I get an error Invalid column name 'column_name', because our mssql database server is setup to use CASE SENSITIVE and UPPER CASE column names, whereas doctrine is forcing all my column names to be lower case. How do I set up doctrine to either preserve sensitivity (better) or make them upper case? </p>
