Jerome,

What data access are you going to use? (Ado, DAO or some exotic engine?).

Assuming ADO:

Add a record: rsYourResultSet.Addnew
Edit a record: rsYourResultSet.Fields("Fieldname").value = Value
Delete a record: rsYourResultSet.Delete
Search a record: rsYourResultSet.Find "fieldname=" & value

Um.. sparse? Yes, but you didn't provide alot of information to begin with.

I'm using a MS Access Database

 

by: daffyduck14milPosted on 2002-12-17 at 08:37:27ID: 7596146

Duh,

Reread the question. It is real simple. Add a primary key on the fields you do not want duplicate information in. In Access you just say it's indexed (no duplicates). Or set the primary key with the "key" symbol.
