Syntax
UNIQUEID()
Description
UNIQUEID() generates a sequence of eight random digits and letters suitable for use as a unique identifier, 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. The chance of a duplicate ID being generated is virtually zero: just 1 in over 28 trillion.
Return Value
A Text value: a newly-generated pseudo-unique ID.
