Re^2: Generate unique ids of maximum length

in thread Generate unique ids of maximum length

Why a random string and not simply a sequence number? The latter would have the advantage of definitely being unique (besides being trivial to implement), while a random string might (in theory) repeat, and thus not necessarily be "totally unique"... (which means you'd need to check against a hash holding already used IDs). Also, for the reverse lookup a simple array would suffice.

Good points - especially the array part - I was just thinking about the 'strings of the same length' part. Either way, the point is the same. Just a something something...	[reply]
