How do I allow duplicate entry in Microsoft Access 2000?
Friday, November 27th, 2009I am creating a database for our CDs and I have more than one CDs for an artist and it won’t let me go any further, tells me that I must "change the data in field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries."
You are better to create 2 tables, otherwise you duplicate a lot of data. Use one table for artist information, give each artist an autonumber ID. Then use an artist_ID field in the cd table to connect each cd to the ID of the artist concerned. Also you are better to use the cd number to identify the disk, in case you ever get another disk (even by a different artist) with the same name. No field with a chance of being used more than once with the same data can be a primary or unique key field.

In the first part of a two-part series, Chris Bryant, CCIE #12933, explains the purpose of an Access Server and clears up some misconceptions regarding these important Cisco home lab devices. Part 2 will show you how to configure an AS. Enjoy!
