Re: xor in PL/SQL

Well, strictly speaking it's not already there. Most CPU's can do XOR between two single words (32-bits in most cases). But when it comes to XOR of strings (of bytes or otherwise) most require code as well.

Having said that, XOR in PL/SQL (and SQL) is long overdue. I lost count of the number of times I could have used it and had to dig out my Karnaugh maps to get an efficient XOR coded...

Listening, Mr Oracle? Pretty please?
