Change an access Primary key with relationships
- by DiegoMaK
I have a database in access 2007 accdb extension , there are more or less 30-40 tables with related primary key "local_number". it is a text primary key with 10 lenght.
How can I change the length of this primary key to 30 WITHOUT delete previosly all the 30 relationship.
2,A similar question.
I need add a compose primary key to my PK "local_number". I need Add a "Date" as composed PK.
Then access just allow this if I first delete all relationships.
How can Avoid this warning and change my PK ignoring this message.
