Hi, folks:
it might not be a Perl specific question, but I'd rather find a Perl solution. :-) I have over 25,000K unique strings(5-50 chars in length) and I need to generate an 12-digit unique/random hex-decimal ID for each record and import them into MySQL. new records having a different field value might be inputed later. So far, I can use MySQL's auto_increment column to make an absolutely unique seed and adjust them to 12-digit. But it looks not flexible for new input in the future.. Is there any method(hashing,MD5 or whatever) that I can use with Perl to generate 12-digit unique/random keys against over 25,000K records.
many thanks
lihao
