ok ... Stick with DBD::ODBC
just for style and maintanablity of your code stick to DBD calls rather than using ODBC or Sybase unique calls.
but you allready knew that .....
the largest problem I've had with ODBC is geting a connected to NT servers. Once connected ODBC/MySQL/Oracal all work the same.
as for using ODBC on linux rather than any other sys.... if you use DBD::ODBC the same code should run on linux 2.2 2.4 or win2k with out changes.
