title: What does OBJECT_ID do in SQL Server?
body: <p>I'm trying out the usage of <code>OBJECT_ID</code> and found <a href="http://msdn.microsoft.com/en-us/library/ms190328.aspx" rel="nofollow">the following entry</a> in MSDN:</p>
  
  <blockquote>
    <p><em>"Returns the database object identification number of a schema-scoped object."</em></p>
  </blockquote>
  
  <p>What is database object identification number and what is schema scoped object. Seems like I'm more confused than initial.</p>
