Is it possible to create a table without any keys?
WORKAROUND:
None. A key is available in every entity by default. It's been created as every entity should have a primary key. The default key is empty and is not included in final SQL code generation. If you VERIFY the model by clicking a table and: Model | Verify model ... a warning is generated because every entity should have its PK. If you do not want warnings to be displayed click a table, then go to Model | Verify model ... and clear the Show Warnings checkbox in the Model Verification dialog.
STATUS:
An enhancement request has been submitted for consideration in a future version of TDM.
