Before you can edit the data in Enterprise Manager you need to add a
unique constraint or unique index. To facilitate that it may help to
use SELECT DISTINCT to eliminate duplicates and copy the data to a new
table. It rather depends on just how you want to eliminate the
duplicate data. You can Google for lots of previous posts on this topic
in this group and in the microsoft.public.sqlserver groups.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
