Hi,I have two tables in question, a "letter_history" table and a "customers" table. I want to create a primary key in the letter_history table which is made up of the customer_id field and a mailing_id field. I have done this and the primary key symbol is displayed next to each of the two fields. I now want to be able to create a relationship between the letter_history table and the customers table via the customer_id field which exists in both tables. When I try to do this i receive the following message:The columns in letter_history do not match an existing primary key or unique constraint.I think this may be something to do with the letter_history primary key being a composite/compound key, but I'm not sure.Any help would be greatly appreciated.CheersPaul |
