 To my opinion GUIDs type need to provide the following in the database.

1. GUID type must accept the correct string format(s), with of without
extra '-'
2. GUID type must internally be stored as small as possible.
3. GUID type must be comparable with == , != , LIKE and (NOT) IS NULL
4. GUID type must have the ability to be indexed, grouped, ordered,
DISTINCT... but not MAX(), MIN() or SUM()....

Where do you see a need for LIKE on a GUID?
