Unable to create index because of duplicate that doesn't exist?

Question

I\'m getting an error running the following Transact-SQL command:

CREATE UNIQUE NONCLUSTERED INDEX IX_TopicShortName
ON DimMeasureTopic(TopicShortName)
         


        

Answer 1

It should have specified the duplicate key value in the error message. "The duplicate key value is (' ', ' ', ' ') The statement has been terminated. You have duplicate values that need to be addressed.
