VARCHAR2(64) |
| GUID | STRING128 | NA |
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |
