The possibility of having to merge data from several independent test stations is what made me think of using GUID in the first place. I don't think there's a better way.
As for wasted space, the few extra bytes needed by GUID is a drop in the bucket compared to the blobs I'm storing. If I was sure I wouldn't be merging data I might use timer ticks as my ID, but I'm not sure and I can't take the chance. -Bill > -----Original Message----- > From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users- > boun...@sqlite.org] On Behalf Of Stephan Beal > Sent: Wednesday, April 23, 2014 11:51 AM > To: General Discussion of SQLite Database > Subject: Re: [sqlite] BLOBs and NULLs > > On Wed, Apr 23, 2014 at 6:56 AM, Keith Medcalf <kmedc...@dessus.com> > wrote: > > > You don't ever really need a GUID at all.
