title: DB2 SQL query to compare 2 schemas
body: <p>I have been unable to find a solution in my searching for this throughout the web, most responses recommend a tool, which leads me to believe this may be very difficult with an SQL query or something, but...</p>
  
  <p>I have been told to write a query for our DB2 database, using Toad to interface, that will compare 2 schemas and provide a result if there are any differences.  I know this capability exists in Toad, but for some reason our DBA does not want to use it.  Purchasing additional software is not an option.  </p>
  
  <p>I have very limited SQL knowledge/experience, and this is one of my 'learning' tasks.  I have not made much progress and am feeling very stuck.  Can anyone offer me suggestions?  The help is greatly appreciated!</p>
