ALTER TABLE DROP COLUMN failed because one or more objects access this column : <p>I am trying to do this:</p>

<pre><code>ALTER TABLE CompanyTransactions DROP COLUMN Created
</code></pre>

<p>But I get this:</p>

<blockquote>
  <p>Msg 5074, Level 16, State 1, Line 2
  The object 'DF__CompanyTr__Creat__0CDAE408' is dependent on column 'Created'.
  Msg 4922, Level 16, State 9, Line 2
  ALTER TABLE DROP COLUMN Created failed because one or more objects access this column.</p>
</blockquote>

<p>This is a code first table.  Somehow the migrations have become all messed up and I am trying to manually roll back some changed.</p>

<p>I have <em>no</em> idea what this is:</p>

<pre><code>DF__CompanyTr__Creat__0CDAE408
</code></pre>
