What is the method for obtaining a UUID in Oracle?

You can use the SYS_GUID() function in Oracle database to obtain a Universally Unique Identifier (UUID). This function returns a value of type RAW, representing a globally unique identifier.

Here is an example of obtaining a UUID using the SYS_GUID() function.

SELECT SYS_GUID() AS uuid FROM dual;

This query will return a RAW type value containing a UUID.
