Correct description for uuid() with argument #274

Closed MartijnR closed 3 years ago

MartijnR commented 4 years ago

As @alxndrsn discovered, a GUID and UUID are the same and should be 128 bits, so it probably say something like:

Without arguments, it returns a random RFC 4122 version 4 compliant UUID. With an argument it returns a random string with the provided number of characters.

It would have been better to not support an argument for uuid() and create a new function for a random string of a custom length instead. But presumably, we'll have users that are using an argument.

Agreed. Unfortunately, the uuid(len) variant has been there since the beginning of time.
