Syntax
Basic Form
UNIQUEID()
UUID Form
UNIQUEID("UUID")
Description
Basic Form
UNIQUEID() with no arguments 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: just 1 in over 4.2 billion.
UUID Form
UNIQUEID() with the UUID argument 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.
Return Value
A Text value: a newly-generated pseudo-unique ID.
