title: is it safe to install mySQL on windows server 2003 when MS SQL 2005 express already exists?
body: <p><b>[edit]</b><br />
  I should note that I need to do this on a live production server.  The MS SQL Server is already attached to our website and supports a 3rd party ERP package.  I want to set up a separate database that I can code against for some auxiliary pages and internal-use apps) which will be completely independent (mostly for security, but also because I prefer mySQL) from the ERP solution.<br />
  <b>[end edit]</b><br /></p>
  
  <p>The MS SQL 2005 express db is already installed and in use, so I don't want to hose it.</p>
  
  <p>Will this create problems, or have you done it successfully?</p>
