Title: calculate a hash string from all fields
Post by: Robert Iliuta on March 20, 2015, 03:38:51 AM

Hallo,


I would like to add a hash field to keep the hash from all fields...and when a field has changed the hash changed and this way I know something has been changed and I do some process.
How can I loop trough all fields and create one big string and then generate a hash from that string?
I have also cryptonite but I don't know how to loop trough fields... :-(

thank you for any tips!

Robert

you don't need to loop through the fields.
All tables have a "record" which is a GROUP - ie a string over the whole record.
So

Hash(fil:record)
will give you the hash of the whole record.

Cheers
