Re: Sybase vs Oracle - which is better?

Sybase and oracle are both relational databases. Relational theory is concerned with set processing, which is far more efficient than row by row processing. What you described is using a cursor in browse mode, which is not such a major problem and may be quite valid in the case you described. Updating using cursors however is extremely inneficient. I have rewritten cursors for clients using stored procedures & temp tables and they always run faster.
