Default persistence enforce set to true would anyway delete association table's lines - codefluent

Question

The property defaultPersistenceEnforce is set to true at project level. We consider following example.
Meeting ----*> Contact <---- Case
When we have one contact referenced in the table Case, the call of stored procedure Contact_Delete() would fail as exepected.
But when there's no reference in table Case the execution of stored procedure Contact_Delete() would delete the lines inside association table Meeting_Contacts_Contact.
It doesn't make much sense since I would like to prevent such behavior. In particular, I didn't specify any cascade relationship for deletion.
I would like to make sure that tuples are not being erased in such tables, in particular when there are referenced.
How can I have the stored procedure Contact_Delete() to only delete Contact and don't consider references ?
Thanks for your answer,
Enclosed the model part and the definition of Contact_Delete stored procedure.

Answer 1

This is by design. The delete procedure generated for an entity also deletes the records of the many to many table.
A simple workaround is to create a CFQL method DeleteById:
DELETE(Id) WHERE Id = #Id
This method generates the following stored procedure:
CREATE PROCEDURE [dbo].[Meeting_DeleteById]
(
#Id [uniqueidentifier]
)
AS
SET NOCOUNT ON
DECLARE #deletedcount int
DELETE FROM [Meeting]
WHERE ([Meeting].[Meeting_Id] = #Id)
SELECT #deletedcount = ##ROWCOUNT
SELECT #deletedcount
RETURN
GO
