Ok, sorry. In the message, some acronyms, including PK, are automatically expanded if you set the correct option. Under "Message view setup", at the top of the message, select "Enable / disable acronyms".
>But I didn't say though that PK is new with VFP9. What I said/meant was, i'm a new user of VFP9 and just starting to learn about it and I'm asking what does "PK" means.
Another common abbreviation is FK for foreign key, and (less common) CK for "candidate key". A candidate index allows you to specify additional fields that have to be unique, but by definition, only one index defines the primary key.
