Pseudo-unique ID
Returns a newly-generated pseudo-unique ID (Text value).
Syntax
Basic Form
UNIQUEID()
UNIQUEID() (with no argument) generates a sequence of eight random digits and letters suitable for use as a unique identifier within the app, such as a row key.
The generated ID is not strictly unique. Instead, it is sufficiently random as to be effectively unique for all practical uses within the app. The chance of a duplicate ID being generated is virtually zero.
UUID Form
UNIQUEID("UUID")
UNIQUEID("UUID") generates a version 4 universally-unique identifier (UUID), a sequence of random digits and letters suitable for use as a unique identifier everywhere. While the generated ID is not guaranteed to be unique, it is sufficiently random as to be effectively unique for all purposes.
