VARCHAR2 assumes character data that matches whatever encoding you've set in your database for character data.

if you insist on forcing Oracle to treat that data as a valid WE8ISO8859P15 character string, yes indeed.

What you need to do is store that encrypted data as a BLOB. In which case Oracle treats it as a binary string, no translation. Which is what you want if you're doing the encryption yourself. Received on Mon Feb 04 2008 - 04:13:46 CST
