Indexing to avoid duplicates

Indexing to avoid duplicates

Indexing to avoid duplicates

i have a few tables in SQL Server2008 that have been in use for a while, i am trying to create indexing on a serial number field to avoid duplicates, i know in access i can change the table field to index no duplicates, in the server do i use the indexes and keys option by right clicking the field and then changing the unique to yes?? will this do what i need or am i totally off base here. thanks

RE: Indexing to avoid duplicates

Changing the index to unique will do what you expect it to. Specifically, it will enforce your data to be unique.
