Oracle VARCHAR2 Column Size
14 Nov 2013
Recently a fellow database architect claimed that in Oracle the type VARCHAR2(255) means a string of 255 bytes, not characters. There is not much difference between the two in the English-speaking world. It matters though if you want to handle people with names like Kołłątaj. (Not that Hugo Kołłątaj – a famous Polish 18th century politician – would ever use any of our systems, but he became our byword for all non-pure-ASCII names).
