title: Negative database IDs in SQL Server
body: <p>Can database Ids be negative in SQL Server?  </p>
  
  <p>I know that you can have a total 32767 (for both 32 bit and 64 bit) <a href="http://msdn.microsoft.com/en-us/library/ms143432.aspx" rel="noreferrer">(Maximum Capacity SQL Server)</a></p>
  
  <p>I know that the first few database Ids are reserved for master, model, msdb and tempdb and 32767 is the hidden system resource database.</p>
  
  <p>I have never seen a negative database Id but I would like to confirm that it is not possible.</p>
