uuid3() and uuid4()

string uuid3(string namespace, string name)
string uuid4()

The functions uuid3() and uuid4() generate a UUID version 3 or 4, respectively.

Examples

  • uuid4() returns da7e73a7-8dca-4123-b671-7997d7fd2fb8 or a similar, random UUID

  • uuid3('6ba7b810-9dad-11d1-80b4-00c04fd430c8', 'example.com') returns 9073926b-929f-31c2-abc9-fad77ae3e8eb.

  • uuid3("foobar") is not really a call that conforms to the standard, since no namespace (a UUID) was included, but returns 3858f622-30ac-3c91-9f30-0c664312c63f anyway.
