Hi Pranav,
Robert is on the correct track. Also, what exact version of ASE ODBC Driver? Sound like older 15.0 version. Changes were made in the charset translation/conversion/handling since early 15.0 version - on ASE ODBC 15.7 version there is more flexibility. However, in using cp850 to store your characters - what are the column data types?
Cheers,
-Paul
