according to Wikipedea: the number of random version 4 UUIDs which need to be generated in order to have a 50% probability of at least one collision is 2.71 quintillion,
<calculation omitted> This number is equivalent to generating 1 billion UUIDs per second for about 85 years, and a file containing this many UUIDs, at 16 bytes per UUID, would be about 45 exabytes, many times larger than the largest databases currently in existence, which are on the order of hundreds of petabytes.[17][18] so... why couldn't I have gotten this duplication on a power ball ($720 million) or mega millions ($1.7 Billion) ticket :p Chip On Mon, 29 Oct 2018 14:53:29 -0400, Chip Scheide via 4D_Tech wrote: > UUID value ="E092AB501E1D41F5A5D15B56E835D2EE" > this value appears to be duplicated in my database! > > ideas? thoughts? > Chip > --------------- > Gas is for washing parts > Alcohol is for drinkin' > Nitromethane is for racing > ********************************************************************** > 4D Internet Users Group (4D iNUG) > Archive: http://lists.4d.com/archives.html > Options: https://lists.4d.com/mailman/options/4d_tech > Unsub: mailto:4d_tech-unsubscr...@lists.4d.com > ********************************************************************** --------------- Gas is for washing parts Alcohol is for drinkin' Nitromethane is for racing ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
