Subject Re: hash.cc From Marc VdB <dbase@dbase.db> Date Thu, 29 Feb 2024 12:34:33 +0100 Newsgroups dbase.getting-started Hi Sean, if i should guess, i would say you are using the gethashx-method. This one is used to add a second layer of security by making sure, that the hash-values never are the same, even if the input is the same. If you use the gethash  (without x) equal input will give equal output. This said, if not for special circumstances, a direct comparison to check for differences would be faster, because you don't have to calculate the hash value HTH, Marc > If I may ask a noob question. I wanted to use the hash function to check whether data within a dataset has changed between two days. This to my brain seems like a good use. > > When I run the hash, the values populated change for each iteration I run. So each rows hash is never the same which null and voids my use case - am I potentially doing something wrong (more like what am I doing wrong?!). > > Sean
