Hi Guys,

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.

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!

beside: I#m using udl-files to setup the connections (Microsoft OLE DB - driver)

what can I do?
