Question

I have a database with two tables, PROCESS (PK Process_Id) and PROCESS_STAGE (PK Stage_Id, FK Process_Id).

At least I think I have set this up – in the foreign key relationships dialogue box I have

• Foreign key base table: PROCESS_STAGE,
• Foreign key columns: Process_Id,
• Primary/unique key base table: PROCESS,
• Primary/unique key column: Process_Id.

I have also set enforce for replication and enforce foreign key constraints to ‘Yes’.

But I can still do the following things which break this relationship:

1. Delete items from PROCESS which have references from
   PROCESS_STAGE

What do I need to do to correct this?

Thanks!

Answer 1

Try using SQL to create the foreign key

ALTER TABLE PROCESS_STAGE WITH CHECK ADD
    CONSTRAINT FK_PROCESSTAGE_PROCESS 
          FOREIGN KEY (Process_Id) REFERENCES PROCESS (Process_Id)

If this still fails, look at the tables schema/owner: you may have more than one table and you’re using the wrong one. Example:

• dbo.PROCESS_STAGE
• deed02392.PROCESS_STAGE
