title: how to use different oracle character sets in one application
body: <p>i'm developing a 32bit Client-Application with Delphi. From this application I need to connect to databases on two different servers. First databse character set ist WE8MSWIN1252, the other server decodes with WE8PC850. Setting the client NLS_LANG parameter to the correct value solves correct sql-query results.</p>
  
  <p>Unfortunately this (the client character-set) seems only to be recognized on applications startup (first connect to oracle). I need to change the client-characterset at runtime. Oracle client seems to store the character set an application used to connect! </p>
  
  <p>beside: I#m using udl-files to setup the connections (Microsoft OLE DB - driver)</p>
  
  <p>what can I do?</p>
