title: Error when trying to import from Database with Pandas and SQLAlchemy
body: <p>I am using portable python 2.7.6.1 and I want to import a query from an oracle database into python pandas. I have searched a couple of examples and came up with the following code:</p>
  
  <pre><code>from sqlalchemy import create_engine
  import pandas as pd
  
  engine = create_engine('oracle://user:pass@host:port/schema', echo=False)
  df = pd.read_sql('select * from databasetable', engine, index_col = index)
  
  print df.describe()
  </code></pre>
  
  <p>The program stops at the 'pd.read_sql'-statement with this Error Message: </p>
  
  <pre><code>AttributeError: 'module' object has no attribute 'read_sql'
  </code></pre>
  
  <p>The Database connection is working and according to the examples this code should work. Can anyone help?</p>
