#11 DbCreator Oracle: is GUID a valid column type?

[Thomas Mueller]

dbcreator/u_dzDbCreatorCreateOracle.pas maps dtGuid to the Oracle type GUID, with the TODO "does Oracle actually support this type??". If it does not, creating a table with a GUID column fails; Oracle usually stores GUIDs as RAW(16) or as a 36 character VARCHAR2.

Needs checking against Oracle and, if necessary, a different mapping.

From the TODO scan in issue 12 of dzlib's ISSUES.md.
