FoxPro 9.0 - Free Table (DBF) - Set Fields to be Primary Keys
I have a free standing DBF FoxPro Table that I would like to set a couple of Fields to be Primary Keys so that Duplicate Data doesn't get entered.
I haven't been able to figure out how to do it.
Thanks,
Mark

Stay tune...next week for sure!

Still haven't had time to test out these solutions, but I've had to move onto other projects and tasks.
I didn't want to leave this question hanging out there forever so I gave each of you the same amount of points. If I ever do get back to this...I will try your solutions and follow up at that time.
Thanks again!

FoxPro
Visual FoxPro (VFP), and its predecessor FoxPro, is a data-centric, object-oriented, procedural, database programming language and IDE from Microsoft last released in 2007 that still has some active use due to its low cost of deployment and fairly rapid development. In 2008, Microsoft released a set of add-ons for VFP's xBase components to allow interoperability with various Microsoft technologies. It allows data processing against its native file-based data tables or database servers such as SQL Server.

If your app uses SET DELETED ON setting then the Candidate index should contain FOR clause:
INDEX ON STR(AccYear,4)+CurrCode TAG YearCurr FOR !DELETED() COLLATE "Machine" CANDIDATE
It will avoid problems with "invisible" duplicities.
